| Abstract: | The optimum design for the soil nailing structure is a double-level optimum problem.A technique of the improved genetic algorithm combining with complex method is discussed.This technique uses the improved genetic algorithm to adjust the design parameters of the soil nail and applies the complex method to search the critical sliding surface.The results show that this technique is used successfully to solve this problem;and the optimum design is more economic than the common one. |
