摘　　要：铁路路堑边坡失稳滑塌是雨季最常见的病害,会对铁路行车安全造成严重威胁。鉴于此,文章针对国外某铁路工程设计面临的土质深路堑边坡稳定问题,借助钻孔岩芯鉴定,通过室内物理力学试验获取关键参数,对边坡进行稳定性分析,提出了支挡工程优化设计方案,以期为同类工程勘察设计提供参考。The instability and collapse of railway cutting slopes is the most common disease in rainy season,which will pose a serious threat to railway traffic safety.In view of this,this paper aims at the stability problem of soil deep cutting slope faced by a foreign railway engineering design.With the help of drilling core identification,the key parameters are obtained through indoor physical and mechanical tests,and the stability of the slope is analyzed.The optimization design scheme of supporting engineering is proposed,so as to provide references for the survey and design of similar projects.
