| 摘 要： | 边坡稳定性的关键问题是确定最危险滑动面(潜在最危险滑动面)和边坡的稳定系数。国内外一般是采用先假定边坡滑移模式,然后近似确定最危险滑动面,再求近似的边坡稳定系数的方法来分析边坡的稳定性,但假设的边坡滑移模式难以反映边坡滑移的实际状态。因此本文探索利用遗传算法搜索最危险滑动面,并得到最小稳定系数及对应的最危险滑动面曲线,取得了较好的效果。

| Abstract: | How to ascertain the sliding surface and the factor of safety(FS) is the key problem of slope stability.The failure model of a slope is supposed at first and then the sliding surface and the factor of safety are computed approximately during analyzing the slope stability all over the world.However,the hypothesis cannot reflect the real state of slope sliding.In this paper,the critical failure surface with the lowest value of FS is computed and the better result is got by means of GA. |
