Development of Safety Monitoring Network Analysis System for Underground Caverns and Its Application

Uncertain risk factors universally exit in underground engineering projects during construction and operation. Developing an analysis system for monitoring information to avoid risk is necessary. An advanced, reliable and extendable risk monitoring information analysis system for underground caverns has been developed using visual programming technology, SQL Server database and dynamic link technology. The system has apparent advantages in areas of remote real-time sharing, dynamical and visual analysis and abnormal alarm of the monitoring information. It was applied to manage and analyze the monitoring information of an underground cavern project group, which improved the efficiency greatly and made the monitoring results be timely, exactly and visually fed back to the designer and constructor. The analysis results indicated that the lower of high side walls are the risky areas which should be paid more attention to.
