Slogan of sichuan-tibet railway Construction

The construction period of sichuan-tibet railway will exceed 10 years, which is almost the most difficult railway to build. Why hasn't it been repaired after 10 years? This is because the terrain built first is very complicated, including all kinds of strange terrain, and there are great climate challenges. In addition, the total construction mileage is also very long, so it takes a long time. Next, I will explain it to you in detail. 1. The terrain is very complicated.

We may see only a few kinds of railway landforms every day, such as plains or peaks, but sichuan-tibet railway is very complicated, with mountains and plateaus, deserts and snow. Therefore, it can be said that it is very difficult to build a railway in such a place. Every terrain needs to be prepared differently, so it takes a long time to build and there are many difficulties to overcome. 2. The total construction mileage can be said to be the longest.

Another important reason why we need to build 65,438+00 years is that the mileage is very long. Sichuan-tibet railway starts from Chengdu, Sichuan Province in the east and ends in Lhasa, Xizang Autonomous Region in the west, with a total length of1838km. Therefore, such a long length is rare in our country, and it is more than 4 kilometers to cross 2 1 snow mountain, 14. The overall construction is particularly difficult, and it takes a long time to construct together, but once the construction is successful, it is of great significance to us, so it takes a long time to construct. This section of railway has to stand the test of various climatic conditions.

The construction of our railway is really difficult, because in addition to the above difficulties, there are also climate challenges. Almost all seasons are covered along the railway, including spring, summer, autumn and winter, as well as particularly bad weather such as sandstorms. If the railway construction is unqualified, it will be easily destroyed. Therefore, this railway needs to pass the test of various climatic conditions, so the construction is very difficult and the time spent is very reasonable.

To sum up, the reason why the construction period in sichuan-tibet railway can exceed 10 year is that the construction length is very long, reaching1838km. Secondly, the terrain is very complicated, not only with high mountains, but also with snow-capped mountains and deserts, so it is very difficult to build. In addition, there are many rivers and extremely high peaks, including the test of various climatic conditions, so the construction period.
