摘要
介绍运用摄动随机有限元法（ＰＳＦＥＭ）分析顺层岩质边坡可靠性的推导过程。通过实例分析表明，该方法与模拟有限元法相比，计算量明显减小，结构严谨，结果精确。
The process in which the reliability of rock bedding slope is analyzed by applying the perturbation stochastic finite element method (PSFEM) is formulated. By the analysis of an example, it is indicated that the amount of calculation in this method will be reduced remarkably. Its structure is more strict and the result more accurate, comparing with the simulating finite element method.
