摘　　要：本文基于概率理论对某一粘性土坡稳定进行可靠性分析,给出了计算土坡稳定的可靠性指标及失效概率的方法和评价可靠性的标准。该方法与传统的采用单一的安全系数来表示土坡稳定的方法相比,能够表明土坡稳定真实的安全度和失效的可能程度。可靠性分析方法在一定程度上弥补了传统的定值论方法的不足之处。Based on probability theory,the reliability analysis for stability of a cohesive sloping soil is studied in this paper,the calculation procedures of both the reliability index and the failure probability of sloping soil stability and the standard to-estimate the reliability were given compared with traditional method by using a single safety factOr to express the sloping soil stability, this method con indicate the real degreesot both safety of slope statility and possible failure,To a certain extent,the method of reliability analysis can make up for the weaknesses of traditional method of the theory of definit value.
