摘　　要：深基坑支护方案的选取受安全可行、经济合理、环境保护、施工便捷等相关指标因素的影响,且这些指标因素皆具有模糊性的特点.采用层次分析法确定各指标因素的权重,降低了专家对各指标因素进行评判时的主观性,运用模糊综合评判法评价支护方案的优劣,计算得到各方案的综合评价值,从而确定最优的支护方案,结合工程实例验证该方法确定的支护方案最优,支护效果很好.The selection of deep excavation support programs is affected by some indicators factors such as safe and feasible,reasonable economy,environmental protection,convenient construction and so on.However,all these indicators factors have a characteristic of fuzziness.AHP method is used to determine the factors of each index weight.This can reduce the subjectivity of experts judging various indicator factors.Therefore,fuzzy comprehensive evaluation method is used to evaluate the supporting projects,and then the comprehensive evaluation values of the programs are obtained to determine the optimal support program.Finally,combined with engineering examples,the method is verified to determine the optimal foundation bracing program.

关 键 词：模糊综合评判 层次分析 深基坑 支护方案优化
