摘　　要：对于土钉支护结构优化这样一个二重优化问题,采用改进遗传进化算法调整土钉设计参数,并利用复合形法搜索支护结构的临界滑面,从而得出保证工程安全可靠且造价最低的最优设计方案。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.
