摘　　要：以位于新疆库尔勒市境内的希尼尔水库为研究对象,结合地质勘探资料进行了其地质情况及滑移体岩性指标的分析,现状边坡稳定分析结果显示,水库进水渠岩质边坡滑移面大多为软弱结构,会产生直线型、折线型等形式破坏面,滑坡体主滑动带抗剪强度反演结果也表明,滑坡体曾经发生过滑动,虽暂时处于稳定状态,但是危险性极大。通过对全预应力锚索加固、抗滑桩+预应力锚索加固及明挖卸荷等处理方案的比较,最终确定采用施工过程简便、投资节省、处治效果良好的明挖卸荷治理方案。Taking Xinier Reservoir located in Korla of Xinjiang as the research object,combined with the geological exploration data,the geological conditions and the lithologic indexe of the sliding body are analyzed.The results of the present slope stability analysis show that the slip surfaces of the rock slope in the intake channel of the reservoir are mostly weak structures,which will produce liner,broken line and other forms of failure surface.The inversion results of shear strength of the main sliding zone of the landslide body also show that the landslide has slipped in the landslide,which is stable temporarily but extremely dangerous.Through the comparison of the treatment schemes of fully prestressed anchor cable reinforcement,anti-slide pile combined with prestressed anchor cable reinforcement and open-cut unloading,etc.the open-cut unloading treatment scheme with simple construction process,low investment and good treatment effect is finally determined.
