摘　　要：对青藏铁路的调查显示,融沉是路基破坏的主要因素,除此以外还有路基填料的冻胀和压密.本文通过对北麓河典型土样的室内试验,对与多年冻土冻融变形密切相关的冻土物性、力学特性进行了研究.The investigation along Qinghai-Tibetan Railway shows that the main reason for the destruction of embankment is the thaw settlement. Besides, frost heaving and compressibility of the embankment fill must also be considered. By experiment the Beiluhe＇s typical soil sample, this paper studies the the physical properties and mechanical properties which are closely relation to the frost heaving and thaw settlement .

关 键 词：青藏铁路 多年冻土 土工试验 力学特性
