摘要
有限元数值分析是边坡稳定性研究中较为常用的定量分析方法 ,但有限元分析的前处理工作通常比较繁琐 ,从而影响了该方法的整体工作效率。利用GIS软件实现了从计算剖面确定、计算剖面自动绘制到网格自动剖分的全部前处理过程。有效提高了边坡有限元计算的前处理工作效率 。
Finite element method (FEM) is an effective method for the slope stability analysis. However, the pre-process of FEM is time-consuming and miscellaneous. Geographic information system (GIS), as a new information technique, has not only powerful functions in data management and spatial analysis, but also has capability of data processing and plotting. In this paper, through an example, the basic principle and a brief work flow of pre-process in FEM are introduced.
