Many damage phenomenon are appeared after embankment landslide ,such as narrowing the cross-sectional, shorting the water seeps diameter ,and inducing the seepage failure .Based on the Nanjing Xishan river levee engineering , the paper takes an analysis of the internal and external factors which is caused landslide .Using the strength reduction method,the paper analyses the landslide dam after reducing the shear strength parameters of rock mass ,and proposes a comprehensive treatment plan .This research can provide a reference for comprehensive treatment of similar engineering slope .%堤防滑坡后堤身断面变窄, 水流渗径变短, 可诱发堤岸渗透破坏及其他险情. 以南京市西山河堤防工程为例, 对引起滑坡的内因和外因进行分析研究, 通过强度折减法反分析堤防岩土体的临界破坏抗剪强度参数, 并提出滑坡综合治理方案, 为类似水利工程边坡综合治理提供参考与借鉴经验.
