摘要 通过有限元强度折减法计算了乌江沙陀水电站厂房坝段的深层抗滑稳定安全系数,与基于遗传算法的最危险滑动面搜索方法进行了比较,结果表明,两种方法得到的安全系数是接近的,滑动面的位置也基本一致。 The strength reduction finite element method is used to calculate the deep base anti-slide stability safety factor of the power house section of Wujiang Shatuo Hydropower Station. This method is compared with the most dangerous slip surface search method based on genetic algorithm. The results demonstrate that the results of these two methods are fairly consistent each other;and the positions of slip surface are also much consistent.
