摘　　要：以秭归县某高切坡为例,针对该切坡的工程地质条件、水文地质条件、岩体结构特征等,运用赤平投影分析方法判断出该切坡可能的破坏模式,并在此基础上,通过折线滑动法对该切坡的稳定性进行评价.在治理设计中,根据该切坡地形特征和工程地质条件将其分为两个子区,根据各区的特点分别采用抗滑锚杆、系统锚喷并辅以表层防护和地表排水的综合治理措施,为解决库区移民城镇高切坡的分析与治理难题提出了一种新的思路.A high-cut slope in Zigui County was taken for example. Stereographic projection was made use of to judge potential destruction modal based on the condition of engineering geology, hydrogeology and rock mass structure characteristic and so on. Finally, fold-line sliding method was adopted to evaluate the stability this slope. In the treatment design, two areas were divided according to the geography character and engineering geology condition; and comprehensive treatment measures of anti-slide anchor, anchor system with surface-protection and drainage water were carried out respectively according to the characteristics of each area. A kind of new way to solve the problem of high-cut slope in immigrant areas, is proposed.
