Abstract:

Monitoring, which is the core of the informationaided construction of tunnels and underground works, is one of the basic measures to ensure the construction safety and works quality of tunnels. In this paper, the developing status of the analysis and management system of the monitoring data at home and abroad is investigated and the requirements of the system are analyzed. Database management and figure visualization technology and objectoriented data models are used, with the monitoring items of the tunnel works as the application objects, so as to achieve the function of input and storage of the monitoring data, visualization query, timedependent curves and spatial curves forming, regression analysis and report table forming. The module of analysis and forecasting expert database is added to the system on basis of the judgment on the stability of the surrounding rock mass stipulated in the tunnel design standard. In this way, an analysis and management system of tunnel monitoring data is developed. The system is applied in engineering practice, which verifies its reliability and validity. The system can be used as a new analysis tool for the monitoring data acquired during tunnel construction.
