A New Method of Simulating Arbitrary Slip Surface in Soil Slope

The paper proposed a simulating arbitrary slip surface method. For simulating slip surface, select 7 control points, then connect to broken line which is assumed slip surface. Horizontal spacing between 7 control points is not equal, the spacing is arbitrary. Horizontal spacing of general simulating slip surface method is equal. So the proposed method is closer to the actual. For search method, particle swarm algorithm is not easy to fall into local minima, as a global intelligent optimization method, particle swarm algorithm is suitable for search the most dangerous slip surface. Based Janbu method, the paper computed two examples for simple slope and complex slope. The results show that the proposed method is effective.
