| 摘 要： | 将蛙跳算法引入到边坡极限平衡稳定性分析中,详细介绍了蛙跳算法的流程,并对典型土坡进行了计算分析,结果表明:蛙跳算法搜索到的最危险滑动面上较多的点位于软弱夹层内,所得到的安全系数比遗传算法结果更为合理。通过正交试验分析了蛙跳算法各个参数对计算结果的影响,并给出了推荐的参数取值。

| Abstract: | In order to accumulate the related experience of search algorithms in the location of critical slip surfaces of slopes,the frog leaping algorithm is introduced.The flowchart of frog leaping algorithm is explicitly presented and the typical soil slope is analyzed.The results show that more points on the critical slip surface are located in the soft layer than that from the genetic algorithm,the factor of safety calculated by frog leaping algorithm is more reasonable.In addition,the orthogonal test is performed for one typical slope in order to determine the sensitivity of each parameter on the result.The recommended values are provided. |
