摘要: 青藏高原多年冻土地区具有特殊的地质地理环境,形成独特的冻土工程地质条件。论述了青藏铁路沿线的多年冻土分布特征,阐述了由于人类工程活动与自然环境相互作用而引起的冻胀、融沉和不良冻土工程地质现象及其对铁路建设的影响。Abstract: Permafrost area is of special geological and geographic environment. It forms a unique engineering ge-ological condition. The paper-discuses the distribution of permafrost along Qinghai-Tibet Railway and ex-pounds the effect of frost heaving, thaw-settlement and harmful permafrost engineering geological phenomenon which caused by interaction between human activity and natural environment to railway construction.
