Brief introduction of Qinghai-Tibet Highway?

The Qinghai-Tibet Highway starts from Xining, Qinghai Province in the east and ends in Lhasa, Tibet in the west. Let Zhong Da Consulting take you into this asphalt highway with the highest altitude and the longest route in the world.

The Qinghai-Tibet Highway starts from Xining, Qinghai Province in the east and ends in Lhasa, Tibet in the west. The asphalt highway, which was started at 1950 and opened to traffic at 1954, is the highest highway with the longest route in the world, and the shortest mileage, the best road condition and the safest highway leading to Tibet at present. The scenery along the way is magnificent and rich. You can see grasslands, salt lakes, Gobi, mountains, deserts and other landscapes. It is open to traffic all the year round, and it is the busiest road among the five routes to Tibet. Drivers are prone to fatigue after driving for a long time, so there are also many traffic accidents. From time to time, you will see overturned trucks under the subgrade along the way, so you should be extra careful when taking the Qinghai-Tibet line.

Qinghai-Tibet Highway, with a total length of 1937 km, is a national secondary highway trunk line. Its subgrade width is10m, the slope is less than 7%, the minimum radius is1.25m, the maximum driving speed is 60km/h, and the average elevation of the whole line is over 4,000m. Although the altitude of the line is high, the surface of the plateau after climbing Kunlun Mountain is an ancient lake basin landform type with gentle fluctuation.

The route from Xining City to Golmud City passes through high mountains such as Rubber Mountain (3,800 meters above sea level), Wangga Xiushan (3,680 meters above sea level) and Toto Mountain (3,500 meters above sea level), and passes through rivers such as Dashui River, Xiangride River, Gekeguang River, Brazil River, Qingshui River and Hongshui River, with a total length of 782 kilometers, including 564 kilometers in plain and hilly areas. The elevation of the whole section is 2200-3800 meters. The section from Golmud City to Lhasa City crosses Kunlun Mountain (4600 meters above sea level), Huofeng Mountain (50 10 meters above sea level), Tanggula Mountain (5320 meters above sea level), Touerjiu Mountain (5 180 meters above sea level) and other high mountains, and crosses Chuma River, Hongliang River, Qushui River, Xiushui River and Beilu. The elevation of the whole section is above 4000 meters.

The original construction standard of the Qinghai-Tibet Highway is low, and it crosses the Qinghai-Tibet Plateau, with harsh climatic conditions and particularly poor geological conditions. As a result, expressway has been seriously ill since it was opened to traffic, and has been constantly rectifying and rebuilding.

meaning

Before the Qinghai-Tibet Highway and the Sichuan-Tibet Highway were opened to traffic, it took six months to get to 1 year and 1 year (a few months each way) to make a round trip from Lhasa to Xining, Qinghai or Chengdu, Sichuan, relying on people and livestock, braving the snow and cold, and the whole region * * * transported various materials into Tibet100000 tons, with 65,438 imported materials. The highway only takes a few days, which greatly shortens the transportation time between Tibet and other places.

Tibet, the "roof of the world" of the world, is a magical and beautiful place and has always been a Buddhist holy land that many people yearn for. However, because of the steep terrain and steep mountains and rivers, it has blocked its contact with the outside world. 1950 At the beginning of the year, the China People's Liberation Army advanced into Tibet. This heroic army followed the call of the CPC Central Committee and Chairman Mao's instructions of "building roads while marching" and carried forward the spirit of hard struggle with Tibetan compatriots. After going through hardships and overcoming all difficulties, Sichuan-Tibet Highway and Qinghai-Tibet Highway with a total length of more than 4,360 kilometers were built on the roof of the world, which enabled people in Xizang to replace extremely backward modes of transportation with modern means of transportation.

The Qinghai-Tibet Highway is an important link between Tibet and Chinese mainland. In the highway era, it is responsible for the transportation of more than 85% of materials entering Tibet and more than 90% of materials leaving Tibet. It plays an important role in Tibet's economic development and social stability, and is known as the "lifeline" of Tibet.

Comprehensive reconstruction

general idea

1974 began a comprehensive transformation, the highway standard was upgraded to a second-class highway, and asphalt pavement was added. The reconstruction project from Xining to Golmud was completed on 1978. By the end of 1984, more than 70% of the reconstruction project had been completed from Golmud to Lhasa.

The reconstruction project of Qinghai-Tibet Highway is extremely arduous, especially paving asphalt pavement in high-altitude permafrost regions, which is unprecedented in all countries. According to the ice content in the ice layer of soil foundation, engineers and technicians in our country adopt the method of filling the roadbed with enough height to protect the frozen soil, so that the heat absorbed by the pavement will not affect the frozen soil foundation below the roadbed, and adopt drainage facilities for the roadbed to prevent the surface water from eroding the roadbed, thus achieving the purpose of stabilizing the roadbed. After years of operation observation, the reconstructed road section is in good use.

The reconstruction project of Qinghai-Tibet Highway 1975 started, which is the first black pavement project in the alpine permafrost region in the world, with an investment of 760 million yuan, and it is the largest project in China highway history.

achievement

1In August, 1985, the all-black pavement paving project of Qinghai-Tibet Highway was basically completed, which greatly improved the transportation efficiency and economic benefits. The transportation cost is saved by 50 million yuan every year, and the traffic density is obviously improved. The maximum traffic volume reached more than 3,000 vehicles per day and night, and the driving speed increased from 20 kilometers per hour to 60 kilometers per hour.

It needs to be better.

However, the asphalt pavement laid in the early stage, the temporary bridges and culverts along the line that are not suitable for heavy vehicles, the hot melt settlement in permafrost regions, and the sections of subgrade frost boiling need to be rebuilt and thoroughly rectified.

Odometer along the line

Qinghai-Tibet Highway (National Highway 109 Xining-Lhasa section) starts from Xining City, Qinghai Province in the north and ends in Lhasa City, Tibet in the south. It is a national secondary highway trunk line, with subgrade width10m, gradient less than 7% and maximum running speed of 60km/h. The Qinghai-Tibet Highway is 528km in Tibet, and the territory from Golmud, Qinghai to Lhasa1140km is managed by Tibet. The Qinghai-Tibet Highway runs through Kunlun Mountain, Kekexili Mountain, Tanggula Mountain and beautiful grasslands in northern Tibet, with an average elevation of more than 4,500 meters.

Traffic guide

From Qinghai to Tibet, you can take a bus from Xining to Golmud first. Golmud is about1100km away from Lhasa, and it takes about 24 hours by car. Most vehicles entering Tibet start from Golmud. Qinghai Chaidamu Transportation Company and Tibet Passenger Transport Company have several buses (domestic cars, imported luxury cars and sleeping cars) to Lhasa every day. There are also many trucks going to Lhasa at the transportation station in Golmud, Tibet, from which you can take a ride. The price can be negotiated with the driver.

A special tourist line (domestic luxury sleeping car) has been opened from Lanzhou to Lhasa, and the special bus passes through Ta 'er Temple, Sun Moon Mountain, Qinghai Lake, Golmud Salt Lake, Tanggula Pass, Gelatantong, Tuotuo River, Naqu, Dangxiong Grassland, Namco, Yangbajing and other scenic spots.

be careful/cautious

Most travel books suggest that it is best to go to the plateau for the first time from the Qinghai-Tibet Highway. Because of the high altitude, almost everyone will have mild or severe altitude sickness. It is usually recommended to fly to Lhasa first, and get off the Qinghai-Tibet Highway when you get used to it.

thermal insulation

The best tourist season is May-10 every year. It's too cold in winter and there are few tourists. Even if you take the Qinghai-Tibet Highway in midsummer, you'd better prepare winter clothes such as sweaters and down vests. Rain and snow are common, and the temperature may drop below 0 degrees Celsius.

pay attention to the diet

There are two kinds of food on the Qinghai-Tibet Highway: most ordinary restaurants are "Sichuan cuisine", and Muslim restaurants are mainly pasta and mutton. Drivers running the Qinghai-Tibet line all know which food is delicious. Travelers can bring some fruits, dried fruits and chocolates.

High altitude area

For self-driving travelers, it is recommended to pass through high altitude areas as soon as possible. The relatively difficult section from Golmud to Lhasa is1100km long, which usually starts at 3 or 4 in the morning and can be reached at night. If you can stay in Naqu, Amdo or Dangxiong, the conditions are relatively better.

Scenery along the line

Sun Moon Mountain in Xining

From Xining to Sun Moon Mountain via Huangyuan, the altitude is 3250 meters. Shandong slope is slightly brown due to the windward slope of summer monsoon and the shade of green grass, while Shanxi is leeward with clear yin and yang. On the west slope, there is a river that flows westward into Qinghai Lake. All the rivers in China are "one river flows eastward", so it is named "Daotang River" because it flows westward. There is a boundary monument between Tang and Fan in Sun and Moon.

Qinghai Lake

Summer Moon Mountain is Qinghai Lake, the largest inland saltwater lake in China. In Mongolian, "Ku Lake" means "Blue Lake". The lake is as vast as the sea, the blue sky is like washing, and the cauliflower by the lake is fragrant and golden. There are several tourist attractions along the east bank of the lake. After crossing the Heima River for 70 kilometers, you can reach the Bird Island Hotel, and the Mongolian yurt guest house nearby is very cheap. From the hotel to Bird Island, there is 15km lakeside road. Because it is summer, in April, the overwhelming excitement of thousands of geese, swans and brown gulls completely disappeared, and only the dark cormorants crouched on the island.

Golmud

There is a bus from Xining Railway Station to Golmud, more than 780 kilometers, 16 hours. Golmud is the western end of Qinghai Province on the Qinghai-Tibet Railway, and it is a transit point for materials entering Tibet. The city has begun to take shape, but its population is only 300,000. Every summer is very busy and crowded, which stimulates the development of passenger transport industry. The upper Kunlun mountain pass is more than 4500 meters above sea level, passing through the unfrozen spring and Wudaoliang. Because it is a newly selected route, Golmud has been to Amdo, and there are few Tibetan settlements. The main routes along the way are road classes, military stations or accommodation hotels.

The source of the Yangtze river

Tuotuo is the intersection of the source of the Yangtze River and the Qinghai-Tibet Line, which is more than 0/00 km away from the source of the Yangtze River in the southwest of Xuefeng, Gladin. Gera Dandong Peak is 662 1 m above sea level, which is the highest peak in Tanggula Mountains. Jianggu Diru Glacier is the largest valley glacier in the southwest of Gladang East Peak, with a flow of 12.8km and a terminal elevation of 5395m, which is the birthplace of the Yangtze River.

Tanggula p.

After passing the 104 class and Tanggula Military Station, you will begin to climb the Tanggula Pass, which is 5200m away. Because the road below the mountain pass is 4900 meters above sea level,

Tanggula, which has climbed over 5206 meters, is just a "hill" with a relative height of 300 meters. However, just on the plateau, at the height where the atmospheric oxygen content is only 60%, there will be obvious discomfort after a short pause, not to mention the long-term pommel horse fatigue. Tanggula killed many people who entered Tibet, making them nervous and pale when talking about Tanggula.

Naqu

Naqu, an important town in northern Tibet, means "Heihe" in Tibetan, with an altitude of 4800 meters. It is a distribution center for livestock products, and Xiaodeng Temple, a famous temple in northern Tibet, is in the town. East to Qamdo, west to Ali, north to Xining and south to Lhasa. It is the administrative, economic and transportation center of northern Tibet.

Dangxiong

80 kilometers south of Naqu is Gulu Hot Spring, and a snow peak stands on the west side. 70 kilometers further south is Dangxiong Town (4600 meters above sea level) under the jurisdiction of Lhasa.

Namtso

Namco, one of the three holy lakes in Tibet, is like a dazzling jasper embedded in Qiangtang Plateau north of Nyainqentanglha Mountain. Mongolian is called "Tengger Caspian Sea", which means "Tianhu Lake". The lake is 47 18 meters above sea level, which is 906 meters higher than the "Lake Titicaca" known as the highest lake in the world. It is the second largest saltwater lake in China after Qinghai Lake. Edelweiss, moss, KOBRESIA and other herbs grow in the vast lake, which is a natural pasture for grazing all year round. For hundreds of years, countless Tibetans have come here devoutly, not for sightseeing, but for turning over scriptures. Tibetan customs, it is the will of the Buddha to go to the lake in the year of the sheep, to the mountain in the year of the horse and to the forest in the year of the monkey. Namco is the holy land of body, language and mind. If you can walk around the lake, you can gain profound knowledge, boundless merits, quit bad habits and hardships, and finally get positive results. Therefore, the auspicious Falun designated Gangdise at the turning point as the Year of the Horse, Namco at the turning point as the Year of the Sheep and Zhari Mountain at the turning point as the Year of the Monkey. During the Sagdawa Festival in the Year of the Sheep (April-May in Tibetan calendar), Qicui Temple, Tashi Duoqie Temple, Guqiong Temple and Duojia Temple near Namco will become full of incense and excitement, and people passing through the temples will flow like running water.
