| 摘 要： | 西区顺层岩质边坡位于四川某露天石灰石矿外，曾发生滑坡事故。在综合研究西区滑坡的基础上，分析了造成西区滑坡的影响因素，探讨了西区边坡的形成条件，采用Ks法、萨尔玛法两种关于边坡稳定性安全系数的计算方法，研究了西区边坡的稳定性．研究结果表明：在天然状态下西区边坡是稳定的，而在持续降雨、生产爆破作业等饱和状态下西区边坡是不稳定的，持续降雨是影响西区边坡稳定的主要因素．

| Abstract: | The west-area slope is located outside a certain open limestone pit in Sichuan province,which is a kind of rock mass bedding slope.Accidents of slope landslide had taken place in history.Based on analyzing the west-area slope,affecting factors inducing the slope accident were investigated and the forming condition of west-area slope studied.The slope safety coefficient was calculated by using the K_S and Sarma methods.The results show that the slope is stable under natural condition and is unstable in water saturated condition.Therefore,the continuous raining is the main factor for the landslide accident in the west-area slope. |
