Analysis:
The Qinghai-Tibet Railway runs from Xining City, Qinghai Province to * * City, * * Autonomous Region, with a total length of 1956 km, including 8 14 km and 1984 km from Xining to Golmud. The newly-built Golmud-* * section starts from Golmud City, Qinghai Province, goes south along the Qinghai-Tibet Highway, passes through Nachitai, Wudaoliang, Tuotuo River and Yanshiping, passes through Tanggula Mountain, and then passes through Amdo, Naqu, Dangxiong and Yangbajing in the * * * autonomous region, and enters the territory of * *, with a total length of 165438+. The construction period is 6 years. The designed annual transport capacity is 8 pairs of passenger cars, and the cargo flow density is 5 million tons. Construction of the new line started on June 29th, 2006 at 5438+0. In 2002, the track was laid from Nanshankou to the south. In 2004, tracks were laid in Amdo in both north and south directions. In 2005, the track was laid through Tanggula Mountain, and the whole line was laid in advance. It will be put into trial operation in July 2006.
Qinghai-Tibet Railway is the plateau 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. The geology along the line is complex, and landslides, mudslides, earthquakes, lightning strikes and other disasters are serious. Frozen soil, cold and lack of oxygen and ecological fragility are the "three major problems" in the construction of Qinghai-Tibet Railway.
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 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".
With the successful track laying of this "Heavenly Road" from Golmud to * * *1142km, the history of world railway construction, the development history of China as a unified multi-ethnic country, and the life history of people in Qinghai * * * provinces have all turned a new page.
The international community calls the Qinghai-Tibet Railway "a great project comparable to the Great Wall". In just over four years, the Qinghai-Tibet Railway, which crosses the roof of the world, has been declared completed, and the century-old dream of all China people, including Tibetan compatriots, has finally come true. This is the embodiment of the remarkable improvement of China's comprehensive national strength in the past 30 years of reform and opening up; It is the sublimation of mankind's continuous understanding, exploration, closeness and integration of the Qinghai-Tibet Plateau for thousands of years. It is a world miracle created on the "roof of the world" by China people in the new period with the national spirit of "challenging the limit and bravely creating the first class".
1954, only three years after the peaceful liberation of * *, the Qinghai-Tibet and Sichuan-Tibet highways joined forces in * * *, and people in Xizang, suffering from traffic congestion and poverty and backwardness for generations, sang and danced to celebrate the first time that the snowy plateau had a "happy road" and a "bright road" leading to the mainland of the motherland. This autumn, in October, on the occasion of the 40th anniversary of the establishment of the * * * Autonomous Region, the door of the "roof of the world" was opened again.
The Qinghai-Tibet Railway was born and opened to the world, and the ancient Qinghai-Tibet land will sail to modern civilization on the steel dragon.
Westerners are the biggest beneficiaries of the Qinghai-Tibet Railway. The convenient transportation in and out of Tibet, the increase of logistics and people flow, and the reduction of freight rate brought by the Qinghai-Tibet Railway can not only promote the rapid development of the tertiary, secondary and primary industries, but also provide continuous impetus for * * * to enhance its self-hematopoietic function and the people to move towards a well-off life. Moreover, it will further strengthen the flesh-and-blood ties between * * * and various provinces, autonomous regions and municipalities in China, enhance mutual understanding and unity between Tibetans and brotherly peoples, and contribute to the natural scenery of the plateau and the ancient snowy civilization.
The Qinghai-Tibet Railway is a landmark project for the development of western China, and it is a popular project to end the long history of impassable trains. At the beginning of the construction, * * * was far-sighted, and clearly proposed to open up an economic, fast, large-capacity and all-weather transportation channel on the Qinghai-Tibet Plateau and build a world-class plateau railway based on people.
Qinghai-Tibet Railway is a miracle in the history of world railway construction and a great achievement that China people are proud of. Faced with the challenges of world-wide problems such as frozen soil, cold and lack of oxygen, and fragile ecology, the builders of Guangtong-Dali Railway lived up to their mission, worked hard, strived for innovation and change, overcame unimaginable difficulties and obstacles, endured unbearable life overdrafts in the "life forbidden zone" again and again, not only paved the railway to * * * at a miraculous high speed, but also scientifically and properly handled the relationship between major plateau projects and environmental protection. In the field of frozen soil engineering technology, it has been at the forefront of the world, creating a record of "zero death" of hundreds of thousands of construction workers due to altitude sickness, cultivating the Qinghai-Tibet railway spirit with the connotation of "challenging the limit and being brave in creating first-class", and bringing new impetus to the economic take-off of Qinghai-Tibet provinces and even the whole China in the new century and the reshaping and carrying forward of the Chinese national spirit in the new era.
