摘　　要：基坑开挖引起环境污染和环境破坏.从地下水位下降、支护结构变形、支护结构施工三个方面分析了地质环境的破坏型式;概述了支护结构施工过程导致的环境污染.通过工程实例,构建评价指标体系,建立模糊数学评价模型,评价结果与环境影响实际基本吻合。Excavation of a deep foundation pit bring about environmental pollution and environmental disruption.From the ground water levels fall,supporting structure deformation,supporting structure construction are analyzed from three aspects of geological environmental damagane types,Summarizes the construction process of supporting structure in the environmental pollution.Through engineering examples,constructing evaluation index system,establish the fuzzy evaluation model,and environmental impact assessment results of actual results.

关 键 词：基坑开挖 环境效应 指标体系 模糊数学模型
