Perturbation stochastic finite element method and its application in the reliability analysis of excavation

摘要

The reliability analysis of excavation by PSFEM (Perturbation Stochastic Finite Element Method) is carried out. The results of a numerical example demonstrae the strength of this method in solving the reliability problems of excavation. With its strict theoretical framework and accurate computational results, PSFEM is a reliable and efficient computational technique in the reliability analysis of excavation.
