Abstract
The index system and evaluation method of safety assessment in the operation stage are established to realize the safety risk assessment and management in the operation stage of urban road tunnel. The index scores are obtained from the fuzzy comprehensive evaluation model, and the overall safety risk grade is derived. In view of the index level with an evaluation level greater than or equal to Ⅲ, special risk assessment is conducted, and safety risk solving measures are introduced. A corresponding safety risk management system platform for urban tunnel operation stage is developed on the basis of the results. The results and application of this study have a certain reference value for managing tunnel informatization based on safety risk management.
