摘要: 为探究城市地下大空间施工过程中事故发生的风险规律和演变条件,采用工程调研与统计分析相结合的方法,开展城市地下大空间建设风险特征与分类研究,并通过理论分析对城市地下大空间工程进行风险评估研究。通过工程案例分析,提出城市地下大空间的定义,将其分为新建明挖单体地下大空间、新建暗挖地下大空间及网络化拓建地下大空间; 将城市地下大空间风险源分为地质、环境、勘察设计、施工及管理因素等,并建立了基于数据库的施工风险源识别方法; 揭示了城市地下大空间施工风险独有的特征: 动态演变性、耦合放大性和高风险性;按照风险的表现形式对城市地下大空间风险进行系统分类。最后,基于指标体系法理论,提出了一种针对城市地下大空间工程的风险评估方法。

Abstract:  To investigate the risk pattern and evolution conditions of accidents during the construction of urban large underground space(ULUS), engineeringresearch and statisticalanalysis methods are employed to study the risk characteristics and classification of ULUS construction. Risk assessment of ULUS is performed using theoretical analysis. Then, through an engineering case study, the definition of ULUS is proposed, and ULUS is divided into newlybuilt opencut, newlybuiltmined, and networkexpansion large underground spaces. The risk sources of ULUS include geological, environmental, survey and design, construction, and management factors, and their identification method is established based on a database. The unique characteristics of ULUS construction risks such as dynamic evolution, coupling amplification, and high risk are revealed. The ULUS risks are systematically classified according to their forms. Finally, a ULUS riskassessment method is proposed based on the theoryofindex system method.
