Abstract: In the utility tunnel project mentioned in this paper, an intelligent operation management system for utility tunnel is established combining with modern informatization technologies including BIM, GIS, IoT, big data and cloud computing, which applies the 3D digital model as the basis and the engineering data center as the core. The real-time monitoring technology is applied to monitor and warn the operation of tunnel facilities, and a unified management information platform is established integrating data management, information inquiry, auxiliary decision, command and dispatch, equipment management and asset management. The implementation of the system ensures the safety in operation of utility tunnel, and realizes the integrated, fine and efficient operation management of the utility tunnel.
