 ABSTRACT

Frozen soils occupy most of the area of western China. In order to support the advance of the development of the western region, the Qinghai-Tibet Railway has been basically achieved to overcome the obstacle of the frozen soils, and opened up a new solution to the worldwide problem. In this paper, the Qinghai-Tibet railway was taken as the background; the basic principles of the following 5 main embankment forms were introduced: the block-stone embankment, ventilation pipe embankment, thermal pipe embankment, sunshine-shield embankment, crushed-rock revetment embankment and the development status were analyzed.

Keywords: Frozen soil; Block-stone Embankment; Ventilation pipe; Thermal pipe
