Rosenblueth方法在斜坡稳定性概率评价中的应用

APPLICATION OF ROSENBLUETH MOMENT ESTIMATION METHOD INTO PROBABILISTIC ANALYSIS OF SLOPE STABILITY

介绍了Rosenblueth矩估计方法的基本原理及在斜坡稳定性概率评价中的应用,给出了斜坡的安全系数、可靠指标和破坏概率。这种方法可有效地将传统安全系数与概率分析相结合,使其相互补充。为建立斜坡稳定性安全系数与可靠度相结合的二元指标评价体系,提供了一种好的方法。以岩村滑坡为例进行了计算,结果与实际相吻合。

The basic principle of Rosenblueth moment estimation method and its application into probabilistic analysis of slope stability are presented. The safety factor,reliability index and failure probability are given with this method. This method can combine the conventional safety factor with probabilistic analysis. A dual index system is setup to assess slope stability with safety factor and reliability index. As an example,the stability of Yancun landslide is assessed,and the results are tallied well with the practical case of the landslide.
