| 摘 要： | 通过强度折减,使系统达到不稳定状态时,有限元计算将不收敛,此时的折减系数就是安全系数。本文对不同坡度的算例进行有限元分析把得到的结果与用简化Bishop法得到的结果进行比较,两种方法得到的安全系数基本一致。这说明将强度折减法用于分析匀质边坡稳定问题是可行的。

| Abstract: | Strength reduction FEM has received increasing attention in the stability analysis of slope.An analysis on slope stability through strength parameters reduction algorithm by finite elements is presented.When the system is instable,the numerical non-convergence occurs simultaneousy.The safety is then obtained by strength parameters algorithm.The results through various examples of the gradient are consistent with the results through simplified Bishop.This shows that strength reduction FEM for the analysis of... |
