Abstract In order to effectively solve the problems of the high incidence of risk events and untimely early warning response in shield construction of urban underground works, based on the concept of risk ranking control and in combination with the research on the intelligent pre-alarm mechanism of shield tunneling parameters, a risk ranking control system platform for shield construction of urban underground works has been developed. The platform mainly includes a full-dimensional collection of shield tunneling equipment parameters and monitoring data, comprehensive information integration, GIS layer display, intelligent monitoring of shield tunneling parameters, intelligent collection of monitoring measurement data, risk prediction and early warning management, system management and other modules. It can realize the functions of intelligent early warning of shield tunneling data overrun, intelligent risk monitoring, dynamic management of construction risks and post-construction risk status control of formed tunnel structures. The development and application of the platform provide a reference example for effectively solving the current problems of difficult shield construction supervision and lagging risk response, as well as the construction of an information-based intelligent control platform for shield construction risks of various types of urban rail transit and large municipal projects in the current period.
