Abstract:Coastal urban utility tunnel has the characteristics of soft foundation and complex external environment，which leads to many safety risk points and dynamic changes of utility tunnel.There are many influencing factors and heavy workload in safety risk assessment.In order to solve the above problems and comprehensively identify the risk of utility tunnel，the risk identification method of urban utility tunnel based on WBS-RBS decomposition structure method，scenario analysis method and expert investigation method was proposed.The comprehensive safety risk identification list of coastal urban utility tunnel during operation and maintenance period was constructed.The risk assessment method（AHP-LS method）combined with analytic hierarchy process and risk matrix method were established.The intelligent risk identification and assessment platform of utility tunnel were developed.Based on the above results，the risk assessment of the utility tunnel in Xuwei New Area was carried out，the comprehensive risk list of the utility tunnel in Xuwei New Area was constructed，and the risk comprehensive value and risk level of each hazard source were obtained.The intelligent identification and assessment of the risk of the utility tunnel in Xuwei New Area were realized，which provided guidance for the safe operation and maintenance of the utility tunnel in Xuwei New Area.

Key words:coastal city;Xuwei nes zone;utility tunnel;risk identification;risk list;risk evaluation;intelligent platform
