摘要： 通过某加筋碎石土边坡的工程实例，现场踏勘初步分析其变形破坏的主要原因，判断其可能的几种破坏模式；采用野外钻探、原位试验及室内土工试验等手段获取边坡各岩土层的物理力学指标，利用GeoStudio软件建立二维地质模型，并进行边坡渗流和边坡稳定性计算。从正常工况和最不利工况两个角度来验证该边坡产生变形破坏的原因及模式，最后得出结论，并预测未来边坡变性破坏的发展趋势，以期为同类型加筋碎石土边坡的设计和施工提供一些参考。

Abstract: This paper presents a case history of evaluating a distressed reinforced soil slope and its possible failure modes. The field investigation, insitu and laboratory tests were performed to characterize the subsurface conditions and geotechnical properties of various soil strata. A two dimensional numerical slope stability analytical model under the seepage conditions was established by using Geostudio software. The stability analyses were performed under both normal operation conditions and extreme conditions. The various failure modes are summarized in the paper based on the analytical results.\=
