| 摘 要： | 介绍了强度折减法的基本原理，在此基础上运用强度折减法分析边坡坡角对边坡稳定性的影响，运用ANSYS软件模拟不同坡角的边坡，分析计算不同坡角边坡的安全系数，通过计算得出不同坡角边坡围岩极限破坏时的折减强度参数，分析研究边坡坡角与边坡安全系数F、边坡围岩极限破坏凝聚力c’及极限破坏摩擦角‘φ’之间的关系。

| Abstract: | The basic principle of strength reduction is introduced by this article. The influence of slope angle on the stability of slope is analyzed based on the principle of strength reduction. Slopes of different angles are simulated with ANSYS, and the safety factors of slopes of different angles are calculated. Strength reduction parameters of destruct limit of surrounding rock with different angles are got. The relationship among slope an- gle, cohesion of destruct limit of surrounding rock and friction angle of destruct limit are analyzed. |
