| 摘 要： | 为防止地铁车站基坑工程安全事故的发生，采用模糊综合评价法，从建设管理、地质勘察、基坑工程设计及基坑工程施工等4个方面，根据层次分析法及专家意见确定了各项评价指标的权重，建立了层次结构的评价指标及二级模糊综合评价模型，对地铁车站基坑工程的安全性进行综合评价；并以上海某地铁车站基坑工程进行实例分析，结果表明:该地铁车站基坑的综合评价为“基本安全”，与实际安全状况吻合，说明了模糊综合评价模型具有较高的适用性和合理性。

Research on Safety Evaluation of Foundation Pit Project of Subway Station Based on Fuzzy Theory |
| |
| Abstract: | In order to prevent the occurrence of accidents in foundation pit project of subway station, the weight of all the evaluation indexes are determined and the evaluation index of hierarchical structure and secondary fuzzy synthetic evaluation model are established by adopting the fuzzy synthetic evaluation method from such four aspects as construction management, geological survey, design and construction of foundation pit project according to AHP and experts’advices so as to carry out comprehensive evaluation to the safety of foundation pit project of the subway station and analyze taking the foundation pit project of a subway station in Shanghai as an example. The results show that the comprehensive evaluation of the foundation pit is "basically safe", showing that the fuzzy synthetic evaluation model has high applicability and rationality in accordance with the actual security situation. |
