摘要
FLAC3D软件在边坡稳定性分析时虽然具有强大的功能,但存在建立模型难度大,费时费力且容易出错。根据有限元强度折减法理论,分别采用了有限元软件ANSYS和有限差分软件FLAC3D建立二维模型,将强度折减理论与FLAC3D软件相结合进行分析,并与ANSYS软件分析的结果进行比较。结果显示,二者的分析结果基本一致,克服了FLAC3D本身在前处理方面的不足。研究表明,用FLAC3D软件进行强度折减法计算,在选择合适收敛标准的情况下是可行的。
Through the shear strength reduction theory and by using the finite element software ANSYS and finite difference software FLAC3D,a two-dimensional model can be built to analyze the stability of a slope.Combining the shear strength reduction theory with FLAC3D software,and compared the calculation result with the result calculated by ANSYS software,it is showed through analysis that both the results are good in agreement,and the strength reduction FEM with FLAC3D software is feasible for the slope stability analysis in selecting the suitable convergence criteria.
