青藏铁路7月1日全线试运营,世人瞩目。随着冻土路基、冻土区桥梁、涵洞、隧道、房建、管线等工程的顺利施工,世界上海拔最高、穿越高原多年冻土最长的青藏铁路,堪称“世界冻土工程博物馆”。专家称,青藏铁路穿越世界上最复杂的冻土区,不少冻土工程措施都是国内外首创,可谓集冻土工程之大全。上世纪80年代,由于冻土区筑路技术问题得不到解决,不得不使青藏铁路在中途的驿站——格尔木划上休止符。能不能正确地认识冻土?破解冻土的奥秘?建设世界海拔最高、难度最大的高原铁路,其背后存有许多鲜为人知的故事。
Qinghai-Tibet Railway on July 1 across the board trial operation, the world’s attention. With the smooth construction of the permafrost embankment, permafrost bridges, culverts, tunnels, houses, pipelines and other projects, the Qinghai-Tibet Railway, which has the highest elevation in the world and the longest permafrost crossing the plateau, is called the “World Museum of Frozen Soil Engineering” . Experts said that the Qinghai-Tibet Railway traverses the most complex permafrost regions in the world. Many of the frozen soil engineering measures are pioneered at home and abroad, which can be described as a collection of frozen soil engineering. 80s of last century, due to the technical problems of road construction in the permafrost area can not be resolved, had to make the Qinghai-Tibet Railway in the middle of the post - Golmud draw a rest symbol. Can you correctly understand the frozen soil? The mystery of cracked frozen soil? The world’s highest elevation, the most difficult plateau railway, there are many little-known story behind.
