This paper using the method of risk analysis of the structure on the risk identification,combined with Analytic Hierarchy Process ( AHP),Delphi method and fuzzy mathematics theory,establish risk factors set,determine the factor weights and evaluation matrix,build a fuzzy evaluation model. Paper in Wuhan subway station to the wall,for example,the risk assessment method was verified according to the results for the risk response measures in the process of underground continuous wall construction.%利用风险分析结构法对地连墙施工进行风险识别，结合层次分析法、Delphi法和模糊数学理论，建立了风险因素集，确定各因素权重和评判矩阵，构建出模糊评价模型，并以武汉地铁车站地连墙工程为例，验证了该风险评价方法的实用性。
