基于ANSYS与FLAC的边坡稳定性对比分析

Comparative Analysis for Slope Stability by ANSYS and FLAC

ANSYS是在国内应用广泛的基于有限单元法的数值模拟软件,而FLAC是基于有限差分法的数值模拟软件。二者都能应用在边坡稳定性分析当中,而二者的准确性和二者结果的差别则少有研究。以1987年澳大利亚计算机委员会委托B.Donald和P.Gima设计的ACADS的边坡稳定分析的考核题第一道,一个二维均质土边坡作为算例,然后再结合一个工程实例,从而对两种软件的结果进行准确性与对比分析。

The finite element software ANSYS and finite difference software FLAC are widely use in China now. They all can use to analyze slope stability, but there is little analysis for the precision and the difference of resuits with the result calculated by ANSYS software and FLAC software. A two-dimensional model can be built to analyze the stability of a slope by ANSYS and FLAC. The results prove the reliability of the conclusion.
