摘要： 丹江口水库区内安移民集中居民点和集镇居民点的建设形成一系列的高切坡，给城镇居民生命财产安全带来较大的威胁，高切坡防护是地质灾害防治工作的重要组成部分。以位于丹江口的一处高切坡为例，探讨了高边（切）坡稳定性影响因素，采用极限平衡法及工程地质类比法等分析方法对其稳定性进行了计算分析和预测评价，最后设计采用了“削坡+挂网喷锚+浆砌石挡墙+截排水沟”的工程治理方案。

Abstract: A number of high cut slopes are formed due to the construction of relocation community of the immigrants from the pool area of Danjiangkou Reservoir. Some of these high cut slopes might have a potential safety hazard to the life and properties of the residents. The safety of these slopes is of an integral part of the geological hazard preventions and is also a critical portion of the prolonged safety issue for the relocation communities. This paper presents a case history of the evaluation of a high cut slope. Factors that affecting the stability of the slope are discussed and the safety of the slope are evaluated by the limit equilibrium method and geological engineering analog method. The mitigation of measure utilizes a comprehensive method: the combination of flatten slope with shotcrete on the wire meshes; mortar stacked masonry retaining wall; cutoff ditch at the crest of the slope.
