摘　　要：山区铁路沿线复杂的地形条件以及恶劣的地质状况会给列车运行带来极大安全隐患。本文对一山区铁路路基边坡溜坍病害进行调查,对其发生原因进行了分类总结,将该山区铁路路基边坡溜坍病害归纳为坡面冲沟内堆积层溜坍、软岩风化物汇水地形浅层溜坍、白云岩溶蚀沟槽内全风化物溜坍3类。对不同类型的溜坍病害提出了分析评价方法及针对性的整治措施。可作为防治和快速处理溜坍病害的依据。The complex terrain conditions and bad geological conditions along the mountain railway will bring great security risks to the train operation.Based on the investigation of the topsoil slip disease of the railway subgrade side slope in a mountainous area,the causes of the topsoil slip were classified and summarized.The topsoil slip disease of the railway subgrade side slope in this mountain area can be classified into three types including topsoil slip of accumulation layer in the gully on slope,topsoil slip of shallow layer in the catchment topography of soft rock weathered materials,topsoil slip of completely weathered materials in the dolomite dissolution trench.This paper put forward the analysis and evaluation methods and targeted treatment countermeasures for different types of topsoil slip diseases,which can be used as the basis for prevention and rapid treatment of topsoil slip diseases.
