Why was the Qinghai Tibet Railway built, and the reason why the Qinghai Tibet Railway was difficult

For the sake of the exchange between the East and the West, it is also developing.

I have a good interchange with the west!

Hello, here's why: The Qinghai-Tibet Railway is currently the longest plateau railway in the world that crosses the permafrost. The permafrost of the Qinghai-Tibet Plateau is extremely sensitive to temperature, and the freezing of permafrost and the thawing of the panicle mill occur repeatedly and alternately (with the expansion and contraction of temperature), which poses a threat to the safety of railway operation. The Qinghai-Tibet Plateau has low latitude, high altitude and chaos, strong sunshine, and solar radiation has a great impact on the permafrost. The permafrost of the Qinghai-Tibet Plateau has the characteristics of high ground temperature, thin thickness, and the development of the heat and melting of the hot tribe, and the situation is complex and unique. The Tibetan Plateau has frequent tectonic movements.

Summary. Hello, happy to answer for you! Reasons for the success of the construction of the Qinghai-Tibet Railway China's comprehensive national strength has been significantly enhanced, and it has the material foundation for the construction of the Qinghai-Tibet Railway; China's scientific and technological level has been significantly improved, and the vast number of scientific and technological workers have overcome many problems in the construction of plateau railways; The builders of the Qinghai-Tibet Railway have carried forward the spirit of hard work and self-improvement; Wait a minute.

The Qinghai-Tibet region has become a unique region due to its towering terrain and is known as the roof of the world. It is the birthplace of the Yellow River, the Yangtze River, the Lancang River (known as the Mekong River in foreign countries), the Brahmaputra River and many other major rivers. The Qinghai-Tibet Railway, located in its internal core, is the highest and longest plateau railway in the world today.

There are abundant solar, geothermal and hydro energy resources.

Answer: For you to find out, why the Qinghai-Tibet Railway can be successfully built: China's comprehensive national strength has been significantly enhanced, and it has the material foundation for the construction of the Qinghai-Tibet Railway; The scientific and technological level of our country has been markedly improved, and the vast number of scientific and technological workers have overcome many difficult problems in the construction of the plateau trembling branch imitation railway.

In order to help you solve the problem comprehensively, it also provides you with relevant information: the Qinghai-Tibet Railway can be successfully built this series of super projects, so that the world sighs, you must know that the construction of railways in high-altitude areas has been a global problem, China has become the first country to overcome this problem, providing countries with the experience of borrowing things to learn from, I believe that under the efforts of construction workers, the domestic people will live better and better, and the foundation will be more and more concerned by the world.

The first phase of the Qinghai-Tibet Railway project started construction in 1958.
