舟曲县峰迭乡水泉沟西南滑坡成因机制及稳定性分析

水泉沟西南滑坡是超深层特大型碎石土老滑坡，在前缘局部塌滑、冲沟加剧发育以及降雨等诱发作用下，其存在破坏失稳可能性，严重威胁舟曲县新区人民生命财产安全。根据该滑坡的变形破坏特征，对其成因机制及稳定性进行了分析，并在此基础上提出了“地表截排水＋锚杆框架＋谷坊坝”的综合治理措施。

The genesis mechanism and stability analysis of the southwest landslide in Shuiquangou Fengdie of Zhouqu

The southwest landslide in Shuiquangou is an old landslide with super deep gravel soil .It exists the possibility of instability failure because of the local collapse of the leading edge ,gully development and rainfall ,w hich poses a great threat to residents of Zhouqu county .According to deformation and failure characteristics of the landslide ,the paper analyzes the genesis mechamism and stability of the landslide . On this basis ,the paper puts forward a comprehensive prevention measure of “drainage+ anchor‐frame+check‐dam” .
