| 摘 要： | 文章采用多语言联合编程的方法进行边坡稳定的有限元可靠度分析.前处理部分采用的是有限元通用分析软件ANSYS的APDL语言,用其编写的程序模块可方便地用于有限元网格的划分,以得到有限元计算所需的结点坐标信息、单元结点编号信息、约束结点自由度信息等内容;有限元主程序采用的是VISUAL FORTRAN语言,它可进行基于强度折减法及基于滑面应力分析法的边坡稳定定值法有限元计算,以求解边坡的安全系数及其对应的滑面位置;亦可进行基于强度折减法及基于滑面应力分析法的边坡稳定有限元可靠度计算,以求解边坡的可靠指标及其对应的滑面位置;后处理部分采用的是MATLAB语言,它可方便灵活地绘制网格图、等值线图、滑面位置图及曲线图等各种图形.各种语言之间通过文本文件进行数据的传递,不必另外编写各语言间的接口程序.

| Abstract: | The finite element reliability analysis of slope stability is carried out by using the method of multi-language programming.The APDL of the general purpose finite element software ANSYS is used in the preprocess part,which is mainly used for the meshing of the slope section so as to get the information on nodes' coordinates,numbering of the nodes of each elements,and the degree of freedom of constraint nodes and so on.The VISUAL FORTRAN is used in the main part of the finite element reliability analysis pro... |
