The Development Of Tunnel Monitoring Remote Database System

The monitoring, one of three elements of NATM, is very important for the design and construction of the highway tunnel. Based on the monitoring data, the stability of the rock and the supporting structure can be obtained. The monitoring data is necessary for the modulation of construction. Based on the monitoring on-site, organization of the monitoring data is studied, and one new standard of the monitoring is found. The tunnel monitoring remote database management system is set up using the technology of database and Web. The alarm value and alerting system of the monitoring is discussed in the tunnel engineering and the alarm value and alerting system of the monitoring in the highway tunnel with two lanes is recommended finally.The research is in detailed as follows:First, because of the significance of the monitoring and the problem of the engineering management, based on the monitoring of the tunnel, one new standard of the monitoring and section-line-point of the monitoring data organization are found.Second, the tunnel monitoring remote database management system is based on the monitoring on-site. The system consists of many functions such as equipping monitoring section, imputing data, inquiring data, deleting data, forecasting data, writing report, editing report, uploading report and so on. The tunnel monitoring database system has been used to the JingWuHuang project in Jiangxi province.Third, the alarm value and alerting system of the monitoring are discussed. Based on practical data and the method of FEM, the alarm value and alerting system of the monitoring in the highway tunnel with two lanes is recommended.The practice shows that the tunnel monitoring remote database management system improves the efficiency of the monitoring and the level of the information management in the tunnel.
