摘　　要：探讨了水泥土墙支护结构优化设计方法,建立了以水泥土墙的有效宽度、嵌固深度和置换率为决策变量的优化设计模型,提出了水泥土墙支护结构参数遗传进化优化设计计算方法,讨论了设计计算参数对优化计算结果的影响。并给出了两个工程计算实例,计算结果表明本文方法可得到既安全可靠又经济合理的最优设计方案。Cement-soil retaining wall (CSRW) was usually designed on the basis of the trial and error method, which was not only complicated, but also difficult to find out the reliable and economic solution. In this paper the optimization design method of CSRW was discussed, and an optimization mathematic model for CSRW was set up, which took the effective width, the embedded depth and the replacement ratio of CSRW as its decision variables. Genetic algorithms (Gas) were introduced to optimize the design of CSRW, and the influence of structure parameters of CSRW on the optimization design was discussed. Two examples were given to verify the presented method. The comparison of computed results show that the reliable and economical design can be obtained by the proposed method.
