| 摘 要： | 在不同区域采用不同的本构模型进行边坡稳定性分析,能有效地消除有限元分析中的边界效应,真实地反应出边坡的受力状态。应用强度折减系数法得到边坡的稳定安全系数,并与极限平衡法的结果进行比较。分析高边坡和带有软弱夹层的边坡,得出较满意的结果。

| Abstract: | Two kinds of stress-strain relationship are used for different areas to evaluate the stability of slope,where the boundary effect can be eliminated efficiently and the natural state of slope can be simulated. The slope safety factors acquired by strength reduction are compared with those by equilibrium method. Using the method,two examples including a steep slope and a slope with weak layer are shown,and then satisfied results are gotten. |
