摘要： 介绍了土质和岩质边坡常用的稳定性分析方法，对框架预应力锚索支护中预应力锚索数量、锚索锚固长度以及基于Winkler弹性地基模型框架体系内力的求解进行了说明。以贵州省毕节市某边坡为工程实例，对边坡的稳定性系数进行了分析，设计了该边坡的框架预应力锚索支护方式的参数，根据此方案进行施工取得了良好的加固效果。

Abstract: Frame structure with prestressed cables as an effective supporting system in the slope stability remediation has been widely applied in the construction. This paper introduces the stability evaluation methods in soil and rock slopes. The approaches of estimating the number as well as the length of ground anchors in the frame system are presented. The stress analysis of the frame structures are based on the Winkler's elastic foundation theory. A case history of a slope in Bijie City, Guizhou illustrates the application of this method. The stability of this slope as well as the design parameters of the frame system are presented in the paper.
