| Abstract: | Based on the researches on the nonlinear finite element analysis of stress fields in soil slopes, the nonlinear finite element techniques for analysis stability of soil slopes is integrated with a ant algorithm, which is a new optimization method of artificial intelligence. The ant algorithm optimization technique is used in search of the non-circular slip surface associated with the minimum safety factor of soil slope based on its stress fields from finite element analysis. Finally the feasibility of the technique is demonstrated with an example of stability analysis. |
| Keywords: | engineering geology stability of soil slope critical slip surface finite element methods ant algorithm optimization techniques |
