摘要/Abstract

摘要： 研究一套适用于地铁深基坑施工风险评价的指标体系和方法，用以分析评判项目施工风险等级，指导和改进现场施工风险管理.首先，依据事故树分析(FTA)、“4M1E”系统安全理论和文献分析等，构建包含29个指标的地铁深基坑施工风险评价指标体系;然后，结合风险耦合理论分析风险因素间的交互作用，建立基于C-OWA算子和相互作用矩阵法的施工风险评价模型.结合某地铁深基坑施工项目案例，应用该评价指标体系和方法计算施工风险等级为中等风险，此结果与项目实际施工情况相符，从而验证了本文方法的可行性.

Abstract: A set of index system and method suitable for risk assessment of subway deep foundation pit construction was developed to analyze and judge the risk level of a project， and to guide and improve the risk management of site construction. Firstly， the risk evaluation system with 29 indexes of subway deep foundation pit construction was established according to FTA， 4M1E system safety theory and literature analysis. Secondly， the interaction between risk factors was analyzed with the risk coupling theory， and the construction risk evaluation model is established based on C-OWA operator and interaction matrix method. As a case， the construction risk level of a subway deep foundation pit construction project was calculated by the evaluation index system and method proposed， and the results show that the risk level was medium， which accords with the actual situation of construction project， thus verifying the feasibility of the method above mentioned.

Key words: subway deep foundation pit; risk coupling theory; interaction matrix; C-OWA operator; accident tree analysis
