叙述了概率风险分析（PRA）在边坡稳定性评价中的应用。几位作者都认为，在某些情况下，这种方法是实用的．然而，尽管发表了大量的这个论题的资料，PRA并没有在岩土工程中得以广泛应用．概述了传统的确定型分析方法与概率方法之间的差异。特别强调在设计执行过程中后者在经济结构体系内的潜在受益，并详载了典型实例，以说明这种方法的实际应用．
The application of probability risk analysis (PRA) in slope stability evaluation is described. Several authors agree that in some cases, this approach is practical. However, PRA has not been widely used in geotechnical engineering, despite the large number of published papers on this topic. Outlines the differences between the traditional deterministic and probabilistic methods. Particular emphasis is put on the latter’s potential benefits in the economic structure during the design implementation, and typical examples are given to illustrate the practical application of this method.
