What kind of road is the Qinghai-Tibet Railway?

The Qinghai-Tibet Railway runs from Xining City, Qinghai Province to Lhasa City, Xizang Autonomous Region, with a total length of 1956 km. Among them, 8 14km, 1979 and 1984 from Xining to Golmud were paved and put into operation. The Golmud-Lhasa section under construction starts from Golmud City, Qinghai Province, and goes south along the Qinghai-Tibet Highway to Lhasa City, the capital of Xizang Autonomous Region, with a total length of 1 142 km, of which the existing line from Golmud to Nanshankou is newly built112 km, with a reconstruction of 32 km. The construction of Qinghai-Tibet railway is facing severe challenges of frozen soil, cold and lack of oxygen and ecological fragility. This project is arduous, demanding and difficult.

The Qinghai-Tibet Railway started construction on June 29th, 20001year. In that year, the investment was11.80 billion yuan, and the reconstruction of the existing line from Golmud to Nanshankou was completed. The subgrade from Nanshankou to Wang Kun was basically formed, and the frozen soil test section was started, which won the first victory. In 2002, it invested 5.32 billion yuan; The main project under Golmud-Wangkun line was completed, the main project under Wangkun-Chumar River line was basically completed, and the main project under Chumar River-Buqiangge line was completed by more than 80%; Track laying began on June 29th, and it reached Kunlun Mountain smoothly at the end of the year. This year is a comprehensive year for the construction of the Qinghai-Tibet Railway, with a planned investment of 5.6 billion yuan. By the end of July, the total investment was 2.39 billion yuan and the total construction started was 8.89 billion yuan. At present, the frozen soil project in the northern part of Tanggula Mountain is taking intensive measures, laying tracks and erecting beams to advance to the hinterland of the plateau, and key projects such as Tanggula ridge-crossing section and Donnan section have been started, and the all-round battle has reached its climax.

Qinghai-Tibet Plateau is known as "the roof of the world" and "the roof of the earth", and it is the source of rivers in China. The Qinghai-Tibet Railway, built in this primitive, unique, fragile and sensitive geographical and ecological environment, is the railway with the highest altitude and the longest route in the world. The highest point of the railway crossing Tanggula Mountain is 5072 meters above sea level, 960 kilometers above sea level, and more than 550 kilometers in frozen soil area. Effective protection of ecological environment in the construction of Qinghai-Tibet railway is an important task of Qinghai-Tibet railway construction, and it is also the focus of attention at home and abroad. The CPC Central Committee and the State Council attached great importance to the ecological environment protection of Qinghai-Tibet Railway construction. Comrade Zhu Rongji demanded that the State Council's spirit of strengthening the ecological environment protection of the Qinghai-Tibet Plateau should be conscientiously implemented, and that the ecological environment of Qinghai-Tibet should be well cared for and every grass and tree in Qinghai-Tibet should be well protected. It points out the direction for the ecological environment protection of Qinghai-Tibet railway construction.
