摘　　要：在对陇海铁路宝兰二线马家磨车站扩堑边坡稳定分析过程中,采用有限单元法,对采集的随机数据,依据概率与统计原理,进行边坡破坏概率分析,同时也确定了应力、应变在边坡的分布状态。从而为马家磨车站扩堑边坡工程支护加固提供理论依据。In stability analysis of cutting slope expansion in Majiamo Station along Longhai Railway Baoji- Lanzhou Second Line, the collected random data is analyzed for the probability of slope failure using finite element method according to the theory of probability and statistics, and at the same time, the distribution of stress and strain is determined in the slope so as to provide theoretical basis for support and reinforcement of cutting slope expansion engineering in Majiamo Station.

关 键 词：可靠度分析 扩堑边坡 边坡破坏概率 安全系数
