Application of perturbation stochastic finite element method in the reliability analysis of rock bedding slope

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.
