摘　　要：针对地铁车站深基坑施工风险因素繁多复杂等特点,借助多级物元可拓理论对风险分析评价,有效预防和减少施工安全事故发生.首先依托RBS理论思想,从风险来源角度全面识别深基坑施工风险,建立基于"人、管、技、材、环"五方面因素的评价指标体系;其次引入三角模糊语言变量将定性指标定量化,采用模糊优先规划理论与熵权法相结合确定主客观权重,削弱专家主观偏好不利影响,建立多级物元可拓理论的深基坑施工风险评价模型,通过综合关联度值评判施工风险等级;最后将模型应用到嘉年华地铁车站深基坑工程实际案例中,表明该深基坑施工风险等级为"三级",评价模型具有可行性与合理性,并提出相应风险控制措施,为地铁车站深基坑施工风险评价提供理论方法和依据.According to the characteristics of complex risk factors of deep foundation pit in subway station,the risk analysis and evaluation of the risk analysis is carried out with the help of multi-grade element extension theory,so as to prevent and reduce construction safety accidents effectively.Firstly,based on the RBS theory,the construction risks of deep foundation pit are comprehensively identified from the perspective of risk sources,and the evaluation index system is established based on the five factors of "people,management,technology,material and environment".Secondly,introducing triangular fuzzy language variables quantifies the qualitative indexes,fuzzy priority planning theory and entropy weight method to determine the subjective and objective weights,weaken the expert subjective preferences,establish the theory of multilevel matter-element extension construction risk evaluation model,through the comprehensive correlation degree calculate and determine the risk level of construction.Finally,the model is applied to the carnival subway station deep foundation pit engineering practice case,shows that the deep foundation pit construction risk ratings for "level 3",the evaluation model is rational and feasible,and put forward the corresponding risk control measures,for deep excavation of metro station construction risk evaluation theory and basis.
