摘　　要：根据深基坑工程的特点,建立了支护方案评价指标体系,采用模糊综合评价的方法,建立一级模糊综合评价模型,并将指标的不确定性进行定量化,结合实际工程运用模糊综合评判法,评价深基坑支护系统方案的优劣程度,并确定最优方案。In this paper according to characteristics of supporting works for deep excavation, an index system for supporting version was established. A one level fuzzy evaluation model was formed with fuzzy mathematical method. The uncertainty of the index factors was quantified, The fuzzy complex evaluation method is applied to evaluating the superior and inferior degree of the bracing system schemes for the deep excavation, and then the optimum scheme is obtained.

关 键 词：深基坑 支护 模糊综合评价 优选
