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. At the groundbreaking ceremony of the Qinghai-Tibet Railway, the country 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.
2. The plateau railway with the highest altitude
The railway crosses 960 kilometers above 4000 meters above sea level. 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 above 4000 meters above sea level, and the highest point is Tanggula Pass at 5072 meters above sea level, which is known as "the closest railway to the sky".
3. The longest mileage through frozen soil.
Qinghai-Tibet Railway is the longest plateau railway crossing permafrost in the world, with a mileage of 550 kilometers crossing permafrost for many years. 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.
4. Create the highest speed of plateau railway.
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.
5. The tallest tunnel in the world
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. On June 65438+1October 65438+September, 2002, the Fenghuoshan Tunnel of Qinghai-Tibet Railway was successfully connected.
6. The longest plateau frozen soil tunnel in the world.
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 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.
7. The railway station with the highest altitude
Tanggula station is 5068 meters above sea level. 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.
8. The longest plateau frozen soil railway bridge.
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, the first long bridge of the Qinghai-Tibet Railway with a total length of 1 1.7 kilometers, and the longest railway bridge on the frozen plateau in the world. It also provides a free migration channel for wild animals such as Tibetan antelope.
9. Highest Railway Bridging and Bridging Base
The Anduopujia base of Qinghai-Tibet Railway is 4704 meters above sea level. In the north of Amdo County, Naqu, Tibet, there is an Amdo Pujia base, covering an area of more than 8,000 square meters and an altitude of 4,704 meters. It is the highest railway bridge-laying 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.
Extended data:
Qinghai-Tibet Railway is listed as one of the four landmark projects in the Tenth Five-Year Plan, ranking first among the key projects of western development 12. Foreign media in China commented that the Qinghai-Tibet Railway "is the most difficult railway project in history" and "it will become one of the most spectacular railways in the world".
The completion and operation of the Qinghai-Tibet Railway has shortened the land transportation time of trade between China and major cities in Nepal from 12 to 18 days to less than one week, promoted the economic development of the backward northern mountainous areas in Nepal, and helped Nepal to independently appear on the world political stage. At the same time, the Qinghai-Tibet Railway has strengthened the ties between other vast areas of China and Tibet, promoted cultural exchanges between Tibetans and other ethnic groups, and strengthened the need for national unity.
