摘要： 以某顺层路堑边坡为研究对象，在详细地质资料基础上，结合赤平投影和平面滑动法对边坡稳定性进行分析，结果表明：顺层边坡稳定性主要受层面控制；边坡在天然工况下处于基本稳定状态，暴雨工况下处于欠稳定状态。设计采用预应力锚索框架加固，并辅以锚杆框架综合治理，加固后边坡稳定性系数满足要求。

Abstract: The stability of a highway roadside incline slope was evaluated by using the combination of geological information, stereographic projection and plane slide methods in this paper. The results show that the stability of this incline bedding slope was mainly controlled by the bedding plane; the slope is stable under natural conditions and is in instable state under the rainstorm conditions. In the stability mitigation design, the prestressed ground anchor cable frame assisted with anchor rod was used.
