摘要
针对青藏高原多年冻土的特点,提出了青藏铁路多年冻土区桥梁设计主要原则,并对不同的基础类型在冻土区适应情况进行分析,提出了适应高原冻土性质的基础应用,最后对钻孔灌注桩的承载力,切向冻胀力和基础沉降量的计算进行介绍。
In this paper, the main principles in bridge design of the Qinghai-Tibet Railway, a railway passes through permafrost regions, are introduces. The adaptability and application of some foundations in permafrost regions are also analyzed.
