用强度折减有限元法分析土坡稳定问题

Discussions on Soil Slope Stability Analysis by Strength Reduction Using FEM

采用土工有限元软件Plaxis8.1研究了强度折减有限元法分析土坡稳定的若干问题,着重讨论了土体参数选用及计算域范围和土体本构参数对该法求土坡安全系数的影响。

In this paper parameters sensitivities on the safety factors of soil slopes are studied in details using finite element code package Plaxis 8.1. It is shown that the results are affected by many parameters.
