| 摘 要： | 在对有限元强度折减法和有限元迭代解法的优缺点分析的基础上，提出了边坡稳定分析的非线性有限元混合解法，该法将有限元强度折减法和有限元迭代解法联合运用于边坡稳定分析，充分利用了两种方法的优点。即由有限元强度折减法搜索边坡可能滑动面，将可能滑动面在网格中画出，由迭代解法逐步迭代求得其滑动面的安全系数。并以算例和工程实例说明了此种方法的正确性和合理性。

| Abstract: | Based on the analysis of the strength reduction FEM and the finite element iteration method,according to the virtues of two methods,a mixed finite element method for slope stability analysis is proposed,which unites the strength reduction FEM and the finite element iteration method together for slope stability analysis.Firstly,the strength reduction FEM is used to find the position of the possible slip surface,and then,the found slip surface is established in the calculational model;lastly,the stability saf... |
