Frog Leaping Algorithm for the Location of Critical Slip Surfaces of Slopes

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.
