青藏铁路冻土地区乌丽山垭口段工程地质选线

Engineering-Geological Route Selection of the Wuli Mountain Segment of the Qinghai-Tibet Railway in Permafrost Regions

青藏铁路沿线的多年冻土区分布范围广泛,冻土不良地质现象发育,线路通过时难以绕避。在翔实勘察和认真分析的基础上,根据多年冻土区铁路选线的原则,对多年冻土分布的乌丽山垭口区域线路方案进行比选。

The area of permafrost is very large in the Qinghai-Tibet Railway, where unfavorable geological conditions develop, and the railway cannot avoid them. In this paper, based on detailed survey and analysis, the schemes of Wuli Mountain Segment selected according to the principles of railway route selection in permafrost regions are com-pared.
