| 摘 要： | 提出了一种便于工程应用的改进模拟任意滑动面策略。针对简单遗传算法容易陷入局部最优值的缺陷，借鉴和声算法产生新解的方式来产生遗传算法中的子代个体。该策略能综合利用整个父体的信息来构建子代。将该方法用于求解两个复杂土坡的最小安全系数，所得结果与已有文献结果比较证明，新型遗传算法能搜索到更小的安全系数，可应用于土坡稳定分析。

| Abstract: | In order to overcome the problem of being trapped into local minima encountered in applying ordinary genetic algorithm to search the critical slip surface of slope, an improved procedure based on harmony search algorithm is proposed. In the searching computation the new offspring is obtained according to the whole information of its parents. The proposed method is applied to calculate the minimum
safety factors of two complicated soil slopes. The comparison of the calculation results with existing examples given by other author shows that the proposed method is feasible for stability analysis of soil slope. |
