| 摘 要： | 本文提出了在边坡稳定性的有限元分析中,用模拟边坡垮落过程的方法确定边坡的潜滑面和安全系数。该法反映了边坡的渐过破坏过程和破坏过程中岩体应力场的变化,并把有限单元法和极限平衡法结合起来,既能给出一个总的滑落体和安全系数,又能展示边坡首先破坏的部位。

| Abstract: | In this paper, a new method used for determining the slip plane of a pit slope and its safety coefficient is presented based on the finite element method to simulate the collapsing process of pit slope. The colla- psing gradually process of pit slope and the change of stress in rock slope mass during the process are reflected. The finite element method can be combined with the method of limi equilibrium analysis. A whole slip mass of pit slope and its safety coefficient as well as the first damaged part of a pit slope can be obtained. |
