To investigate
the risk pattern and evolution conditions of accidents during the construction
of urban large underground space(ULUS), engineeringresearch
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.
