摘　　要：传统的边坡稳定性分析主要采用的是以安全系数为评价标准的设计方法,该法未能考虑不确定性因素对边坡稳定性的影响。本文将蒙特卡洛(Monte-Carlo)法和有限元相结合,计算边坡结构加固前后滑裂带的平均可靠指标。通过此法,将有限元计算结果和可靠度有机地结合起来,开辟了边坡结构可靠度计算的新途径。Traditionally, the slope stability analysis is carried out mainly with the help of a design method which takes the safety factor as the evaluation index. However, this method does not take account of the influence of uncertain factors on the slope stability. In this study, the stability of slope structures before and after reinforcement is calculated by Monte - Carlo method and the finite element method （FEM）. Based on the finite element analysis and the reliability calculation, a new approach to the calculation of slope reliability is put forward.
