摘要

采用遗传算法对基坑支护结构进行优化设计，针对其早熟现象和局部搜索能力差的缺点改进遗传算法。使用自适应策略改进交叉算子与变异算子，在进化后期采用与位爬山法结合的混合遗传算法增强GA的局部搜索能力。对基坑支护结构建立优化设计数学模型，编制了基于遗传算法的基坑优化设计程序。通过实例分析，验证了改进策略的正确性。

Abstract

Supporting structure of deep excavation is optimized using genetic algorithm(GA); and limitation of GA such as poor local search ability and premature is largely enhanced. Then crossover operator and mutation operator is improved while considering the adaptive method; also the combination of hill-climbing with GA enables better local search ability in post-evolution. Mathematic model of deep excavation supporting structure is discussed; according to which a GA software system is developed for deep excavation retaining system. An engineering example is studied; and the results show the validity of the amelioration.
