The structural health-monitoring system for a large bridge is a huge intelligent and integrated information system. Thus, conferring it with a self-checking function through a remote control is an important and difficult task. This article focuses on an integrated monitoring and management platform based on remote-control technology and proposes the overall architecture of cluster control. The platform introduces and designs the following five aspects in detail: bridge-structure network monitoring, power monitoring, system self-test equipment, mission control, and synchronization control. The research findings are applied in engineering practice, and good results are obtained.

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.
