| 摘 要： | 文章基于主应力等差圆提出了一种实用的屈服准则,并将这一准则与强度折减弹塑性有限元数值分析方法相结合,进行了边坡的稳定性分析。对于算例边坡,对比计算与分析表明,利用这种屈服准则所求得的边坡稳定安全系数,与简化Bishop法的计算结果基本一致。

| Abstract: | A practical yield criterion is proposed on the basis of the arithmetic circle of principal stresses,and it is incorporated with the elasto-plastic FEM based on the strength reduction technique for numerical analysis of slope stability.The comparative numerical analyses of example slopes by using different yield criteria are performed.It is shown that the safety factors computed by the proposed yield criterion are almost the same as those obtained by the simplified Bishop's method of limit equilibrium. |

| Keywords: | slope stability elasto-plastic FEM based on the strength reduction technique yield criterion safety factor |
