| 摘 要： | 阐述了在边坡稳定性概率分析中，把岩体强度参数视为随机变量，考虑到边坡工程的风险，用工程类比法确定出整体边坡允许破坏概率和目标可靠性指标，从而选择最佳边坡设计方案。认为破坏概率与安全系数是不同范畴的概念。可靠性概率分析法充分考虑到了影响边坡稳定性的各种因素，其结果更为可靠，并具有更强的适用性

| Abstract: | In the probability analysis of side slope stability,the intensity parameter of rock mass is taken as a random variable,the risk of side slope engineering is taken into consideration,the allowable destructive probability of overall side slope and the realiability index of targets are worked out by means of engineering analogy.therefore,an optimum design is chosen.The study reveals that destructive probability and safe coefficient are different concepts,belong to different domain.The method of fail-safe probability analysis takes all factors affacting the stability of side slope into full consideration.So the result is more realiable and more practical. |

| Keywords: | destructive probability stability of slope side fail-safe probability analysis realiability index |
