| 摘 要： | 用算例证明了概率危险面与定值危险面并不一致。提出了2种方便实用的概率分析方法，即基于定值安全系数程序的组合参数搜索法和在Excel中运用的矩阵公式法。经过比较认为组合参数搜索法虽是近似的，但比传统的定值法更接近矩阵公式法得到的概率危险面，2种方法均可用于工程实践中土坡稳定性的概率分析与评价。

| Abstract: | The critical probabilistic surface does not always coincide with the critical deterministic surface. Two approaches were proposed to apply probabilistic analyses in practical soil slope stability. One is parameter combination searching method based on deterministic factor of safety and the other is matrix formulation method used in Excel. Although the former is an approximation, its result is nearer to the critical probabilistic surface than the conventional deterministic method. However, the two algorithms are practical. |
