After more than five years of hard work, the Qinghai-Tibet Railway will be put into trial operation on July 1 day, 2006, and the dreams of generations will be supported by solid rails. As the highest railway in the world, the opening of the Qinghai-Tibet Railway will completely end the history that Xizang Autonomous Region, which accounts for one-eighth of the country's land area, is closed to railways.
As early as the beginning of the last century, Dr. Sun Yat-sen put forward the idea of building a railway to Lhasa, but in poor and weak old China, even the best idea could only be written on paper and could not be put into practice at all. After the founding of New China, it took only seven months and four days for the builders of New China to build the first Tibetan highway across the Qinghai-Tibet Plateau. Subsequently, the construction of Tibet Railway was put on the important agenda of the CPC Central Committee and the State Council. Under the cordial care of the older generation of central leaders such as Mao Zedong and Deng Xiaoping, the Xining-Golmud section of the first phase of the Qinghai-Tibet Railway was 8 14 kilometers long, and the track was laid in 1979 and put into operation in 1984. However, the construction of the Golmud-Lhasa section of the Qinghai-Tibet Railway was forced to stop due to the economic strength of the country at that time and the technical problems of road construction such as plateau permafrost.
With the enhancement of China's comprehensive national strength and the implementation of the strategy of developing the western region, in 200 1 year, the construction of the Golmud-Lhasa section of the Qinghai-Tibet Railway started, and100000 construction troops went to the Qinghai-Tibet Plateau from all directions of the motherland, which brought unprecedented vitality to the vast plateau and vast snow areas and left countless touching stories on this magical land. "Challenge the limit and be brave in creating first-class", they interpreted the spirit of the Qinghai-Tibet Railway with wisdom, sweat and hard work, overcame the worldwide engineering and technical problems such as frozen soil, cold and lack of oxygen, ecological fragility, and broke the prediction of the western media that the Qinghai-Tibet Railway could not pass the wind and volcano at all, creating a world miracle. The Qinghai-Tibet Railway spans Kunlun Mountain, Tanggula Mountain and Nyainqentanglha Mountain, nine rivers such as Xueshui River, Tuotuo River and Tongtianhe River at the source of five major water systems, as well as Gobi desert, swamp wetland and snowy grassland, just like a steel dragon crossing the roof of the world, it will become the steel artery of the Qinghai-Tibet Plateau.

Fenghuoshan Tunnel, Kunlun Mountain Tunnel, Yangbajing 1 Tunnel, Tongtianhe Bridge, Kaixinling Bridge, Yangtze River Source Bridge, Lhasa River Bridge, the first Gao Qiao-Sanchahe Bridge of Qinghai-Tibet Railway, and the first long bridge of Qinghai-Tibet Railway are1142km in length from Golmud to Lhasa of qingshui river bridge ... Qinghai-Tibet Railway, crossing a series of plateau tunnels.
Qinghai-Tibet Railway is the longest plateau railway crossing permafrost in the world, with a mileage of 550 kilometers crossing permafrost for many years, and it is called "World Museum of Frozen Soil Engineering". 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 ideas 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.
In order to solve the frozen soil problem that puzzles the railway construction in the plateau of the world, the railway scientific research department of China organized scientific and technological forces as early as the early 1960s, and established a frozen soil research base-Fenghuoshan Observatory at an altitude of more than 4,800 meters on the Qinghai-Tibet Plateau. Over the past 40 years, researchers have been observing and recording the changes of meteorology and frozen soil, and accumulated more than120,000 valuable data for the construction of the Qinghai-Tibet Railway. Through a series of advanced technologies, the builders of Qinghai-Tibet Railway not only ensured the safe construction under the conditions of low oxygen and low pressure, but also successfully solved the construction problem of plateau frozen soil. "Wind-volcano permafrost tunnel construction technology" won the first prize of Qinghai Province's scientific and technological progress in 2004, and the second prize of national scientific and technological progress in 2005.
After decades of unremitting hard preparation and five years of construction practice, China railway builders have successively overcome more than 20 worldwide problems in plateau frozen soil construction. The top speed of the Qinghai-Tibet Railway to be opened soon can reach 1.20 km/h, which is much higher than that of frozen soil railways in Russia and other countries, ranging from 40 km/h to 60 km/h.
Before the construction of the Qinghai-Tibet Railway, the relevant state departments made a special study on the climate, environment, species and ecology of the Qinghai-Tibet Plateau. The environmental protection objectives set by the Qinghai-Tibet Railway include: ensuring the stability of frozen soil environment, pollution-free river water quality, effective protection of soil erosion, effective protection of plateau vegetation, free migration of wild animals and no destruction of the landscape along the railway. In order to protect the extremely fragile ecological environment of the Qinghai-Tibet Plateau, the environmental protection investment of the Qinghai-Tibet Railway reached 65.438+0.54 billion yuan. Taking "protecting every plant and tree on the Qinghai-Tibet Plateau" as its own responsibility, the contractors have taken environmental protection measures such as transplanting turf, constructing wetlands in alpine regions, and setting up wildlife migration channels, breaking the old model of "destroying first and then treating" in China's past engineering construction, trying and exploring a new model of environmental protection for major projects in China, which has become the most environmentally friendly in China's traffic history.
The Qinghai-Tibet Railway crosses the no-man's land of Hoh Xil and Tanggula. At an altitude of more than 4000 meters, the harsh plateau climate environment seriously threatens the life, health and safety of builders. The General Command of Qinghai-Tibet Railway Construction put forward "survival first, then production", and all contractors "safety comes first when the military and horses are not moved". Three-level medical institutions have been established along the project, and there is a hospital every 10 km on average, and employees can get effective treatment within half an hour. The extensive use of modern mechanical equipment in buildings has greatly reduced the labor intensity of workers. This fully embodies the people-oriented thought, thus creating a miracle that no one in the participating units died of altitude sickness.

With the trial operation of the Qinghai-Tibet Railway, people flow, logistics and information flow will accelerate the modernization process of this plateau continent. Low-cost, large-capacity and all-weather uninterrupted railway transportation will further activate the internal vitality of the Qinghai-Tibet Plateau and make the ancient plateau more open and full of vitality.
The potential value of mineral resources reserves in Qinghai Province is 17.2 trillion yuan, accounting for 13.6% of the potential value of national mineral resources reserves. Many domestic and foreign investors have long been optimistic about this market and the rich resources here, but due to the limitation of traffic conditions in Qinghai Province, the development of resources is slow. With the construction of the Qinghai-Tibet Railway, with the care and support of the CPC Central Committee, the State Council and relevant state ministries and commissions, the second-line project of the Lanzhou-Qinghai Railway and the emergency project of the Xige section of the Qinghai-Tibet Railway have started one after another, and the construction of the Qinghai-Tibet Railway has made an important breakthrough, which indicates that the railway passenger and cargo transportation capacity of the whole province has been greatly improved, which will greatly promote the economic and social development of Qinghai and accelerate the pace of resource transformation in Qinghai.
After the completion of the Qinghai-Tibet Railway, Tibet will be integrated into the national railway network extending in all directions for the first time, and the problem of long-distance transportation in Tibet's economic activities will be solved by railway transportation, which will greatly increase the volume of goods entering and leaving Tibet, promote the development of tourism, change backward ideas, create conditions for industrial restructuring, eliminate traffic bottlenecks in Tibet's sustainable development, and create good infrastructure conditions for Tibet's sustainable development.
At the same time, with the opening of the Qinghai-Tibet Railway, tourists will be provided with more convenient and cheap traffic conditions. A large number of tourists at home and abroad will set foot on the plateau and travel by car to enjoy the scenery of plateau lakes and wetlands such as Qinghai Lake, Treasure Beach, Namco, atomic city, Ta 'er Temple, Kunlun Mountain and Tanggula, and the rich and unique plateau tourism cultural resources will be further explored and developed, thus promoting the great development of the tertiary industry in Qinghai-Tibet Province.
The change of the traffic pattern on the roof of the world will profoundly affect the economic and social development pattern of this region. Under the great traction of "railway economy", the industrial resources and cultural advantages of the Qinghai-Tibet Plateau will be further integrated, and the industrial cooperation and division of labor will be more clear under the allocation of market resources, eventually forming the economic region of the Qinghai-Tibet Plateau and becoming an important development pole in the process of western development.
Imagination of "Heaven"
The whistle sounded on the plateau.
Once, Qinghai was far away. A song "In that faraway place" sang her beauty and interpreted her distance;
Today, Qinghai is very close. A "heavenly road" jumps over Kunlun, with the roof of the world at one end and the coastal inland at the other.
The Qinghai-Tibet line, sighing through a thousand years of history, crossing the ancient and silent plateau, piercing the myth of "invincible frozen soil", passing through the world's amazing eyes ... crossing the mountains, breaking the clouds and breaking the fog, the dragon leaped over the "roof of the world", which surprised the world!
Isn't it? The wind rises in Kunlun Mountain, and what you see is the majestic magic of the great cause across the plateau;
Isn't it? The tide surged into the west sea, and what plunged into the bosom was the lofty sentiments achieved by the dream of celebrating the whole world.
Memories linger, more than 1800 days and nights, facing difficulties and twists and turns every moment, facing cold and lack of oxygen; Every moment is the ultimate challenge to life and perseverance, and the greatest consideration to courage and wisdom.
Moved to stay in my heart, 100,000 troops courageously undertook the national mission, united and cooperated with one heart, danced in the air with colorful exercises, wrote the spring and autumn with blood, and cast a monument carried by Tianlu.
From pursuit to dream, from blueprint to reality, it is because of the prosperity of our great motherland, the innovation of great times and the spirit of great nation. When the whistle sounded in a thousand miles of pasture, when the iron dragon roared in the vast snowy area, as sons and daughters of China, can we not be proud of the miracle we created on the earth? Can you not rejoice at the exciting moment of witnessing the opening of the Qinghai-Tibet line?
Qinghai-Tibet line, jumping out of the plateau, watching the oriental red sun, leaping to a new height.
The Qinghai-Tibet line, which is going forward bravely, is forging ahead in the new era, riding the wind from all directions.
