摘要
本文在非线性有限单元法的基础上，引进八节点的狭长单元来描述边坡中的滑动面，同时对于有限元单元网格可调节点坐标进行变更形成新的网格，于是利用原有基本网格架，通过多次有限元分析求出边坡中可能滑动面的稳定系数曲线Ｋ＝ｆ（α），并进而确定最危险的滑动面，在此基础上开展一系列稳定分析工作。
The sliding surface in a slope is described by using enlongated elements with eight nodes on the basis of non-linear finite element analysis in this paper. The coordinate system for adjustable nodes in finite element gride is modified to from a new gride. Thus, using existing basic gride framework, a stability curve for possible sliding surface in slope , K=f (α) ,is found by multiple finite element analysis and the most dangerous sliding surface is determined. On this basis a series of stability analysis is made.
