摘　　要：在总结和分析基本遗传算法及其加速算法的基础上,提出了改进加速遗传算法,并针对非稳定渗流场反分析问题编制了计算程序,最后反分析计算了嶂山闸闸基非稳定渗流场关键计算参数,从而成功计算了闸基渗流场,并指出了闸基存在的主要问题。In this paper, the improved accelerating genetic algorithm is presented and the computational program for the problem of unsteady seepage field designed on the basis of the summarization and analysis of basic genetic algorithm and its accelerating one. Finally, the key computational parameters for the unsteady seepage field of Zhangshan Gate basis is worked out on a back analysis basis, and therefore, the seepage field of the gate basis is successfully computed and the main problem existing in the gate base is pointed out.
