Who can tell me the information of Qinghai-Tibet Railway? I need it for class tomorrow. It's urgent ! ! ! A little shorter.

Brief introduction of Qinghai-Tibet railway

The Qinghai-Tibet Railway has a total length of 1956 km, with an altitude of more than 4,000 meters and 960 km, of which 550 km passes through the plateau permafrost region. Its highest point is located at Tanggula Pass, with an altitude of 5072 meters, and it is covered with snow all year round. It is known as "the closest railway to the sky" and "the highest railway in the world". Building the Qinghai-Tibet Railway is an important strategic decision made by the CPC Central Committee and the State Council at the beginning of the new century. It is one of the four landmark projects in the Tenth Five-Year Plan and the first key project in the western development.

The Qinghai-Tibet Railway starts from Xining City in Qinghai Province in the north and ends in Lhasa City in Xizang Autonomous Region in the south, with a total length of about 1956 km, of which about 846 km from Xining to Golmud was completed on 1984. The Golmud-Lhasa section of the Qinghai-Tibet Railway, which is about to start construction, leads from Golmud Railway Station, an important town in western Qinghai Province, passes through Nanshankou, goes to the hinterland of the Qinghai-Tibet Plateau, passes through Nachitai, Wudaoliang, Tuotuo and Yanshiping, crosses Tanggula Mountain, enters Xizang Autonomous Region, and then passes through Amdo, Naqu, Dangxiong and Yangbajing, and reaches Lhasa, the capital of Xizang Autonomous Region. The route is basically parallel to the Qinghai-Tibet Highway. The Qinghai-Tibet Railway passes through nature reserves such as Hoh Xil, Sanjiangyuan and Qiangtang. Because of its unique environmental protection design and construction, it is also called the first "environmental protection railway" in China.

Qinghai-Tibet Railway is the highest and longest plateau railway in the world today. The area above 4000 meters above sea level is 960 kilometers, and the highest point crossing Tanggula Mountain is 5072 meters. After years of continuous frozen soil section of 550 kilometers, it passes through the 9-degree earthquake intensity zone of 2 16 kilometers. Along the line, it is cold and anoxic, with fragile ecological environment and active crustal movement. Building a railway in such an area is very exploratory and scientific, and the construction task is arduous. The Fenghuoshan Tunnel is the highest railway tunnel in the world. Kunlun Mountain Tunnel is located at an altitude of 4,767 meters, with a total length of 1686 meters, making it the longest frozen soil tunnel in the world.

The construction of the Qinghai-Tibet Railway will end the history that Xizang Autonomous Region is closed to railways, further improve the traffic conditions and investment environment on the Qinghai-Tibet Plateau, and promote the development of Tibet's resources and rapid economic development. It will play an important role in strengthening the ties between the mainland and Tibet, promoting cultural exchanges between Tibetans and ethnic groups, enhancing national unity and benefiting people along the route.

The Qinghai-Tibet Railway starts from Xining in Qinghai in the east and ends in Lhasa in Tibet in the west. It is the plateau railway with the highest altitude and the longest route in the world. After four years of construction, it was put into trial operation in July 2006. It will become the most famous plateau gold tourist route in the world. There are 9 world-class tourist resources such as Ta 'er Temple, Treasure Beach atomic city, Chaerhan Salt Lake, Mount Everest, Lhasa Ancient City and Barkhor Street, 23 national tourist resources, 6 national nature reserves and scenic spots, and 193 ordinary tourist resources. Behind these unparalleled natural landscapes, there is also a Tibetan culture accumulated for thousands of years. Back curtain? Hangdi 1? Hey? Lung curtain? Moving? What's the story?

Train into Tibet

Tibet plateau train is the most advanced train carriage in China at present, with two sets of oxygen supply systems. In order to resist the harsh natural environment such as strong wind and sand and strong ultraviolet rays on the Qinghai-Tibet Plateau, the trains entering Tibet are fully enclosed; The toilet uses a vacuum toilet collector, and the waste water is recycled by special equipment; The joint between carriages adopts a fitted coupler, so there will be no air leakage. In order to cope with the anoxic environment in the Qinghai-Tibet Plateau, the oxygen concentration, temperature and pressure in the train compartment can be kept in balance.

The configuration of each train is almost the same as that of an airplane. There are two sets of oxygen supply systems: one is "distributed" oxygen supply, which keeps the oxygen content of each carriage at 23% through the air in the hybrid air conditioning system, so that passengers can feel like entering the "oxygen bar"; The other is an independent oxygen inhalation interface. If passengers need more oxygen, they can wear a mask to breathe at any time to avoid altitude sickness. If the train walks at an altitude of more than 4000 meters, you will feel as if it is more than 3000 meters. The actual altitude can be reduced by 1000 meters, which can alleviate the discomfort caused by altitude hypoxia.

In addition, the interior decoration of the train entering Tibet is luxurious and modern, which fully shows the ethnic customs of the Qinghai-Tibet region, and a comfortable restaurant and bathroom will be set up. In addition to oxygen supply equipment, medical staff, instruments and medicines are also prepared, and a tourist life support system is established to help guests adapt to the plateau climate smoothly and reduce plateau reflection.

Driving time

The whole running time of the Shanghai-Tibet line train is estimated to be about 52 hours. It is estimated that it will take 45 hours from Chengdu to Lhasa. It is estimated that it will take 22 hours from Xining to Lhasa. Estimated time from Golmud to Lhasa 12 hour.

The Qinghai-Tibet Railway is the best in the world.

The highest plateau railway in the world: the railway crosses 960 kilometers above 4000 meters above sea level, and the highest point is 5072 meters above sea level.

The longest plateau railway in the world: Golmud-Lhasa section of Qinghai-Tibet Railway, with a total mileage of1142km.

The longest plateau railway crossing frozen soil in the world: the railway has a mileage of 550 kilometers crossing permafrost for many years.

The Tanggula Mountain Railway Station at an altitude of 5068 meters is the highest railway station in the world.

The wind-volcano tunnel at an altitude of 4905 meters is the highest frozen soil tunnel in the world.

The total length of Kunlun Mountain Tunnel is1686m, which is the longest plateau frozen soil tunnel in the world.

Anduo Pujia base, at an altitude of 4,704 meters, is the highest Pujia base in the world.

Qingshui river bridge, with a total length of 1 1.7 km, is the longest railway bridge on plateau and frozen soil in the world.

After the completion, the speed of Qinghai-Tibet Railway will reach 100 km in frozen soil section and 120 km in non-frozen soil section, which is the highest speed of railway trains in plateau frozen soil in the world at present.

Environmental Protection of Qinghai-Tibet Railway (Brief Introduction)

Will the construction of the Qinghai-Tibet Railway affect the local environment?

First of all, we must clarify the concept of "environment". From the macro environment, the Qinghai-Tibet Plateau covers an area of 654.38+0.22 million square kilometers, and the scope of railway construction is only within 500 meters on both sides of the line at most, and the Qinghai-Tibet Railway is only 654.38+0.00 square kilometers, which is linearly distributed. It can be said that the construction of the Qinghai-Tibet Railway will not affect the overall environment of the Qinghai-Tibet Plateau. Building such a large-scale project from a small environment,

Within the scope of the construction site, it will definitely have a certain degree of impact on the local environment. Since the design of the Qinghai-Tibet Railway, the First Institute of Tieyi has taken maintaining ecology and protecting the environment as important principles that must be followed. Therefore, most of the Qinghai-Tibet Railway runs along the Qinghai-Tibet Highway, and there are basically no new passages. Moreover, a series of special environmental protection measures were adopted in the design scheme, which minimized the disturbance to the plateau ecology. In the long run, the construction of the Qinghai-Tibet Railway will not only destroy the environment, but also play a positive role in promoting the environmental protection of the Qinghai-Tibet Plateau.

Secondly, Tibet lacks coal resources, and the per capita coal output is only 6 kilograms. The cost of coal transported into the region through the Qinghai-Tibet Highway is very high, reaching more than 600 yuan per ton, while in Xining, the price is only 160~200 yuan. The high coal price has caused an extremely unreasonable energy structure. At present, the main living energy sources in agricultural and pastoral areas are wood and livestock manure. In the northern Tibet where the route passes, the residents mainly rely on the climbing pine growing on the slope as fuel, while the low climbing pine often takes decades to grow, which has caused damage to the fragile local ecological environment. The construction of railway can transport the rich coal and oil resources in northwest China to Tibet through economic and convenient channels to meet Tibet's energy demand, thus making positive contributions to Tibet's changing energy structure, stopping blind deforestation and grassland, and protecting the ecological environment, which is of far-reaching significance.

At the same time, after the Qinghai-Tibet Railway is put into operation, it will inevitably become the main mode of tourism and cargo transportation in and out of Tibet, diverting the huge transportation fleet of the Qinghai-Tibet Highway at present, thus playing a positive role in reducing automobile exhaust emissions and further improving the air quality in the Qinghai-Tibet Plateau.

On the other hand, railway construction will directly stimulate the economic development of Qinghai-Tibet provinces, accelerate the pace of urbanization and industrialization, promote the further adjustment of industrial structure, and transform a large number of herders into people in industries such as industry and construction, thus greatly reducing the load on grasslands and vegetation, protecting ecology and realizing sustainable development, killing two birds with one stone.

Does the Qinghai-Tibet Railway have an impact on nature reserves?

The Qinghai-Tibet Railway will pass through nature reserves such as Hoh Xil and Sanjiangyuan (Yangtze River, Yellow River and Lancang River), but the area where the railway passes is the boundary of the two major nature reserves, and it does not pass through either of them, so it has basically no impact on the ecology and wildlife of the protected areas. At the same time, Tieyi Hospital reserved a special passage for wildlife migration in the design, which is rare in the history of railway construction in China.

What specific engineering measures are beneficial to environmental protection?

1. Protection and restoration of plateau vegetation

Most of the route passes through the plateau meadow area, which is controlled by bad weather conditions and the vegetation growth is very slow. In the process of construction, it is inevitable that some plateau vegetation will be destroyed by borrowing and abandoning soil. For the sections where vegetation is difficult to grow, the method of subsection construction and subsection transplantation is adopted, and each section of subgrade is divided into several construction sections. After the soil borrow yard and subgrade basal turf are shoveled, they will be transplanted to the subgrade slope which has been constructed in advance and the surface of the soil borrow yard after soil borrow, so as to minimize the damage to the surface vegetation.

In the area south of Kunlun Mountain, where the natural conditions are good, the experiment of artificial turf cultivation is carried out, grass species suitable for plateau growth are selected, supplemented by spraying and film mulching techniques, surface vegetation is restored, and green corridors along the railway are built.

2. Frozen soil environmental protection

Frozen soil, especially frozen soil with high ice content, is very sensitive to surface disturbance. Some minor changes in the surface may cause irreversible changes in frozen soil, so special attention should be paid to protecting the environment when building roads in frozen soil areas. From the engineering point of view, it is also very necessary to protect frozen soil and subgrade stability and environmental protection. In order to reasonably select the location of spoil, the borrow point should be a low mound far away from the line, and the borrow depth should not be greater than the upper limit.

3. Strictly control the discharge of "three wastes".

Waste discharge should be strictly controlled in nature reserves such as Hoh Xil, Sanjiangyuan and Qiangtang where the line passes. The closed design of the train not only overcomes the problem of hypoxia in plateau, but also avoids the pollution of waste to the environment along the line. Plateau central station can use oil-fired boilers, electric heaters or environmental protection energy such as solar energy for heating, and garbage will be discharged at designated points in the guidance station for centralized treatment. The domestic sewage of each central station is discharged up to standard after being treated.

4. Strengthen the protection of wild animals.

In the construction and management, employees should be educated on the law of wildlife protection, and it is strictly forbidden to kill and participate in the trade of any wild animals and specimens.

5, elaborate design, strict construction management

In view of the fragile ecological environment of the Qinghai-Tibet Railway, it is difficult to restore vegetation once it is destroyed. In order to minimize the scope of damage, in this design, in addition to the special land acquisition and spoil points, the construction access road and the crossing from the highway to the construction site have also been designed and stipulated in detail, which requires all construction units to strictly abide by. It is strictly forbidden to open construction access roads at will, borrow soil nearby at will, shovel turf at will, or even use bulldozers to directly push soil on both sides of subgrade for filling. At the same time, in the whole construction, the design procedure should be strictly implemented, and it is strictly forbidden to destroy the thermal balance of frozen soil; Even in the construction season, it should be carried out according to the design requirements: if it is necessary to carry out winter construction in frozen soil areas, it must be carried out strictly in winter to avoid destroying the thermal balance and stability of frozen soil.

World's highest 1: the longest plateau railway.

Total mileage of the whole line 1 142 km.

On the sand table of Qinghai-Tibet Railway, the red line representing plateau railway meanders in the sand table.

Qinghai-Tibet Railway is the longest plateau railway in the world, consisting of Xining-Golmud section and Golmud-Lhasa section, with a total length of 1956 km.

The Golmud-Lhasa section of Qinghai-Tibet Railway runs through Gobi desert, swamp wetland and snowy mountain grassland, with a total mileage of 1 142 km.

Starting from Nanshankou Station in Golmud City, the starting point of Qinghai-Tibet Railway, there are towering snow-capped mountains, rivers, vast grasslands and lakes everywhere. Known as "the backbone of Asia" and "the father of Long Mai", Kunlun Mountain is tall and majestic, with an average elevation of 5,500 to 6,000 meters. Known as "the first mountain of Taoism", it is also the birthplace of Kunlun culture and the cradle of Kunlun myth. After crossing the Kunlun Mountain, you will enter the largest "no man's land" in China-Hoh Xil, with an average elevation of more than 4,600 meters, which is known as the "plateau animal kingdom". Rare wild animals such as Tibetan antelope, wild yak, Tibetan wild donkey and snow leopard have brought infinite vitality to the eternal wasteland.

The snowy iron vein crosses the detachment of the source of the Yangtze River, passes through the Tanggula Mountain, the highest point of the world railway, enters the northern Tibet and the Dangxiong prairie, passes through the misty Yangbajing geothermal belt, and finally reaches the sacred "Sunlight City" Lhasa.

After four years of hard work, the last track of Qinghai-Tibet Railway was firmly placed on Lhasa River on June 65438+1October 65438+May 2005, marking the completion of this long line in snowy areas.

The Golmud-Lhasa section of the Qinghai-Tibet Railway is all over 3,000 meters above sea level, of which 965 kilometers are at 4,000 meters above sea level. At the groundbreaking ceremony of the Qinghai-Tibet Railway, state leaders once felt that the construction of the Qinghai-Tibet Railway, the plateau railway with the highest altitude and the longest route in the world, was an unprecedented great feat in the history of human railway construction.

The highest in the world: the highest plateau railway.

The railway is 4000 meters above sea level and 960 kilometers long.

After five years' efforts, 654.38+ 10,000 road-building troops wrote magnificent poems on the "Roof of the World" and built the Qinghai-Tibet Railway, the highest plateau railway in the world.

The Qinghai-Tibet Railway runs through 960 kilometers at an altitude of more than 4,000 meters, and the highest point is Tanggula Pass at an altitude of 5,072 meters, which is known as the "closest railway to the sky".

The Qinghai-Tibet Plateau construction area is cold and anoxic all the year round, and the climate is complex and changeable. The extreme minimum temperature reaches MINUS 45 degrees Celsius. Every year, there are 65,438+065,438+05 days to 65,438+060 days, the maximum snow thickness is over 40mm, and the average oxygen content is less than 60% of that in the mainland. More than half of the areas here are "life forbidden zones" that are not suitable for people to live in.

Altitude sickness caused by hypoxia seriously threatens people's life and health, and also affects the quality and efficiency of large construction machinery in this area. Faced with severe tests and extreme difficulties, the builders of Guangtong-Dali Railway, with the dauntless heroism of "bearing hardships without fear, lack of oxygen without spirit, more will in wind and waves, and more requirements at high altitude", challenged the limit of life and showed incomparable pride, creating a miracle in the history of railway construction in the snowy plateau.

Qinghai-Tibet Plateau is the largest, highest and youngest plateau in the world, and is known as the "roof of the world". Located in the Asian continent, the Qinghai-Tibet Plateau covers an area of about 2.5 million square kilometers, accounting for more than a quarter of the total land area of China. Most areas are above 3,500 meters above sea level, including all of Tibet and Qinghai, western Sichuan, southern Xinjiang and parts of Gansu and Yunnan.

Workers work at the highest point of the Qinghai-Tibet Railway at an altitude of 5072 meters (photo taken on June 6, 2005). Qinghai-Tibet Railway is the highest plateau railway in the world, which runs 960 kilometers above 4000 meters above sea level.

The third in the world: the longest mileage through frozen soil

The mileage of crossing the permafrost is 550 kilometers.

This is the frozen soil section of Kunlun Mountain where the Qinghai-Tibet Railway passes (photo taken on June 18). Qinghai-Tibet Railway is the longest plateau railway crossing permafrost in the world, with a mileage of 550 kilometers crossing permafrost for many years.

The Qinghai-Tibet Railway crosses 550 kilometers of frozen soil.

Frozen soil monitoring system of Qinghai-Tibet Railway started at the end of the month.

If the "world's longest plateau railway" only puts the Qinghai-Tibet railway at the top of the world's length, then the second place in the world may be more realistic, because the Qinghai-Tibet railway crosses permafrost with a mileage of 550 kilometers, which has solved the frozen soil problem that has long plagued mankind in the history of railway and highway construction in the world.

Qinghai-Tibet Railway is the longest plateau railway crossing permafrost regions in the world, with a mileage of 550 kilometers.

Frozen soil is a special kind of soil. Because it contains ice, it is extremely sensitive to temperature and unstable in nature. When the frozen soil layer freezes, its volume increases, resulting in frost heaving. When the permafrost melts, it forms a melting phenomenon. The greater the ice content of frozen soil, the more serious the frost heave and thaw settlement. Severe frost heave and thaw settlement diseases will lead to the deformation of engineering structures, make railway lines lose smoothness and affect the normal operation of trains. The difficulty of building a railway on frozen soil can be imagined.

Qinghai-Tibet Plateau is the highest altitude and the largest permafrost distribution area in the world, accounting for 70% of the permafrost area in China. Compared with high latitude permafrost, permafrost in Qinghai-Tibet Plateau has the characteristics of high temperature, thin thickness and strong sensitivity. The Qinghai-Tibet Railway passes through the most developed frozen soil area.

As early as the early 1960s, China Railway Scientific Research Department organized scientific and technological forces to carry out scientific research in permafrost regions of the Qinghai-Tibet Plateau. After more than 40 years of experiments and research, they have accumulated a large number of frozen soil observation data and achieved many valuable results. After the construction of the Golmud-Lhasa section of the Qinghai-Tibet Railway, the Ministry of Railways attached great importance to the frozen soil problem, organized relevant experts to actively explore the theoretical research, field test, survey and design and scientific construction of frozen soil, and made a major breakthrough in the combination of frozen soil theory and frozen soil engineering practice.

Qinghai-Tibet Railway is the first model in the field of engineering construction in permafrost regions in the world to comprehensively use various engineering measures to solve frozen soil problems. These brand-new solutions and engineering scientific and technological innovations indicate that the permafrost engineering practice of Qinghai-Tibet Railway has been at the leading level in the world.

The fourth in the world: creating the highest speed of plateau railway.

The speed of frozen soil area will reach 100 km per hour.

A truck is driving in the frozen soil area under the Tanggula Mountain (photo taken in June 14).

After the Qinghai-Tibet Railway is completed and opened to traffic, the train will travel at the speed of 100 km per hour in the frozen soil area, which is the highest speed of the train on the frozen soil railway in the world at present.

After the completion, the speed of Qinghai-Tibet Railway will reach 100 km in frozen soil section and 120 km in non-frozen soil section, which is the highest speed of railway trains in plateau frozen soil in the world at present.

Railways have been built in permafrost regions all over the world for more than 100 years, but the disease rate of railways in permafrost regions has been very high, with a speed of only 60 to 70 kilometers per hour. It is reported that the line disease rate of Beia Railway in Russia, which was built in 1970s, was 27.5% at 1994. The disease rate of 1996 line is as high as 45%. The disease rate of railway lines in permafrost regions in northeast forest areas is also high, and trains in the disease areas must pass slowly, which greatly affects the efficiency of railway transportation. In the future, the special trains of the Qinghai-Tibet Railway will be able to run on the Qinghai-Tibet Railway at the speed of 100 to 120 kilometers per hour. Before the Qinghai-Tibet Railway started, frozen soil, cold and lack of oxygen and ecological fragility became three major worldwide road construction problems faced by railway builders. In order to solve the frozen soil problem that puzzles the railway construction in the plateau of the world, as early as the early 1960s, China's railway scientific research department organized scientific and technological forces to establish a frozen soil research base-Fenghuoshan Observatory in the Qinghai-Tibet Plateau at an altitude of more than 4,800 meters. For more than 40 years, researchers have been observing and recording meteorological and frozen soil changes in the frozen soil test section under the snow-capped mountains, accumulating more than 654.38+0.2 million valuable data for the construction of the Qinghai-Tibet Railway.

On March 1 day, 2006, the Qinghai-Tibet Railway started the project to run the test freight train; On May 1 day, a passenger-free train was added to the Jiela section of the Qinghai-Tibet Railway. Through the test, the passenger and freight trains run well.

It is understood that the design speed of the passenger cars about to run on the Qinghai-Tibet Railway is 160 km, and the car body is welded with weather-resistant steel.

The 5th and 6th places in the world: the highest and longest plateau frozen soil tunnel.

Highest plateau frozen soil tunnel:

Fenghuoshan tunnel is 50 10 meters above sea level.

The Fenghuoshan Tunnel is located on the Fenghuoshan at an altitude of 50 10 meters, with a total length of 1338 meters and an elevation of 4905 meters, all of which are located in permafrost on the plateau. It is the highest altitude tunnel in the world and the longest tunnel across permafrost regions, and is known as the "highest tunnel in the world". Before the construction of the Qinghai-Tibet Railway, the western media predicted that the Qinghai-Tibet Railway could not pass the wind volcano at all, because the underground of the wind volcano was all frozen soil, and the thickness of the ice layer exceeded150m. In addition, the harsh natural conditions pose a great threat to the health of the contestants. In the construction of Fenghuoshan tunnel, the builders have successively solved more than 20 major scientific research problems in the construction of frozen soil in the world plateau, such as shallow frozen soil tunnel entry, smooth blasting of ice rock, hot melt control of soil-bearing ice layer and shotcrete protection. On June 65438+1October 65438+September, 2002, the Fenghuoshan Tunnel of Qinghai-Tibet Railway was successfully connected.

In 2002, the reporter walked into the construction site of the Fenghuoshan Tunnel and saw a couplet written by the railway builder outside the tunnel: "White clouds, blue sky and snow fight against the black dragon, and the breeze invites the bright moon to pass through the world's highest tunnel", which showed the builder's lofty ambition and was full of pride and awe.

The longest plateau frozen soil tunnel:

Total length of Kunlun Mountain Tunnel1686m.

Near the Kunlun Mountain Pass at an altitude of 4,767 meters, there is the world's longest plateau frozen soil tunnel-Kunlun Mountain Tunnel, with a total length of 1.686 meters.

Kunlun Mountain is tall and majestic, running through Central Asia. It is called "Asian Spine" and "the ancestor of Long Mai". It snows in Kunlun in June, and it is particularly enchanting in midsummer. Kunlun Mountain Tunnel is located in permafrost region of plateau, with complex geological structure and harsh natural conditions. The tunnel passes through many fault zones, with thick underground ice at the entrance, rock accumulation at the exit, fissure water, groundwater and melted mud flow in the middle, which is called "kaleidoscope" of plateau geology.

It is understood that when the Kunlun Mountain Tunnel was first built, due to lack of oxygen, the construction workers carried 5 kilograms of oxygen cylinders and inhaled oxygen while working, which could consume 6.5438+0.2 million bottles a year.

After a year of hard construction, the Kunlun Mountain Tunnel was successfully completed on September 26th, 2002.

The seventh highest in the world: the highest railway station.

Tanggula station is 5068 meters above sea level.

Qinghai-Tibet Railway: Looking Back at the Battle of Tanggula (Figure)

Tanggula Station of Qinghai-Tibet Railway is located in the hinterland of Qinghai-Tibet Plateau, with an altitude of 5068 meters and a distance of about 600 kilometers from Lhasa. Tanggula Station is a comprehensive passenger and freight station, the highest intermediate station along the Qinghai-Tibet Railway and the highest railway station in the world.

Tanggula Mountain, located in the hinterland of Qinghai-Tibet Plateau, is also called Dangla Mountain, which means "Mountain where eagles can't fly" in Mongolian and is connected with Karakorum Mountain. The air here is extremely thin and the climate is harsh, and the oxygen content in the air is only half that of the inland plain. The continuous snow-capped mountains show the vastness and mystery of the "forbidden zone of life". Being here, you can strongly feel that it is close to the sky, especially at night, and the stars in the sky are big and bright, almost within reach.

Tanggula Mountain Station highlights the characteristics of Tibetan architecture. There is a showroom in the station building, which is mainly used to introduce the scenery of the Qinghai-Tibet Plateau and related knowledge of frozen soil. A stone tablet stands on the platform of the station, which reads "The highest point of the world railway is 5072 meters above sea level" (the highest point of the railway passing through Tanggula Pass). The basic platform is equipped with a sightseeing platform and a canopy for tourists to enjoy the snow scene and photograph the unique scenery of the "roof of the world".

Tanggula Station covers an area of 384.2 square meters. In order to make it convenient for passengers to watch or photograph the majestic peak of Tanggula Station, the railway department carefully selected the station site on the basis of the original station building design, and finally chose the best place to watch the main peak of Tanggula, and built monuments and sculptures, which is one of the best attractions of the Qinghai-Tibet Railway. After Tanggula Station is put into operation, it will use environmental protection energy, mainly electric energy, solar energy and wind energy for heating. The garbage in the station is collected and treated centrally.

World's best 8

The longest railway bridge in plateau frozen soil.

The first long bridge of Qinghai-Tibet railway11.7km.

On the edge of the Hoh Xil National Nature Reserve, the largest "no man's land" in China, a beautiful "Rainbow Bridge" flies under the Kunlun Snow Mountain. This is qingshui river bridge, known as the first long bridge of the Qinghai-Tibet Railway, with a total length of 1 1.7 km, and it is also the longest railway bridge on the plateau and frozen soil in the world. Hoh Xil is cold and anoxic, with scarce vegetation and fragile ecology. At the same time, it is located in the permafrost region of the plateau, and the thickness of frozen soil is more than 20 meters. In order to solve the construction problems in plateau permafrost regions and protect nature reserves, experts in the survey and design of Qinghai-Tibet Railway adopted the measure of "replacing roads with bridges". "Replacing roads with bridges" has solved the problem of subgrade stability in permafrost regions on the plateau. At the same time, the 1300-odd bridge opening between the bridge piers also provides free migration channels for wild animals such as Tibetan antelopes.

This is the world's longest railway bridge on plateau permafrost-qingshui river bridge of Qinghai-Tibet Railway, with a total length of11.7km.

The best in the world

The highest railway bridge base

The Anduopujia base of Qinghai-Tibet Railway is 4704 meters above sea level.

In the north of Amdo County, Naqu, Tibet, there is a bridge base of Qinghai-Tibet Railway-Amdo Bridge Base, which covers an area of more than 8,000 square meters and is 4,704 meters above sea level. This is the highest railway bridge base in the world. The track rows and prefabricated bridges required for the 530-kilometer railway in Tibet are all produced by Amdo Pujia base. Pujia base has played an important role in railway construction, and is mainly responsible for the storage of all kinds of pujia materials, the production of derailment row of rail sleepers, the prefabrication of bridges, the renovation preparation of locomotives and other large equipment. The climate of Anduopujia base is very bad, and the oxygen content in the air is only half that of the inland plain. It is in this working environment that the base workers still set a plateau track-laying record of 8. 1 km in a single day, and the maximum number of tracks produced in a single shift reaches 1 10 rows, that is, 2.75 km, which is also rare in the single-shift production of railway tracks in China.
