摘要： 高切坡防护是地质灾害防治工作的重要组成部分，以位于巫山县的一处高切坡为例，通过对地质特征、边坡类型、边坡成因和结构面形态的分析研究，预测高切坡的破坏模式。采用极限平衡法和工程地质类比法，计算分析其稳定性。最后采用“局部削坡+混凝土格构+挂网喷锚+锚杆工程+排水工程”组合措施进行了治理工程设计。

Abstract: The stability of high cut slope is an important component of the geological hazard prevention system. A slope, which is located within the campus of the Secondary High School of the Town of Wuxia, is analyzed in this paper for the cut slope stability. The potential failure mode of this slope is predicted throughout the analysis of the geological characteristics, cut slope type as well as the structural plane locations. The stability is analyzed by using the limit equilibrium as well as analogic method in the engineering geology. The stability mitigation method used is a combination of local cut, reinforced concrete grid beams, ground anchors with shot crete netting and drainage system.
