Structure health monitoring and safety prewarning system for shield tunnel

Abstract

The invention discloses a structure health monitoring and safety prewarning system for a shield tunnel. The structure health monitoring and safety prewarning system comprises a data acquisition subsystem, a long-distance transmission network, a central data base subsystem, a safety assessment subsystem and a user interface subsystem. The data acquisition subsystem comprises multiple types of sensors and various acquisition units corresponding to the sensors; the sensors are used for acquiring monitoring information of the structure of the shield tunnel, and transmitting processed monitoring information to the central data base subsystem through the long-distance transmission network; and the safety assessment subsystem assesses the structure state of the shield tunnel according to acquired monitoring data, and displays various data to users through the user interface subsystem. The structure health monitoring and safety prewarning system is disclosed for the long-term structure safety requirement of the shield tunnel; the use stability and durability are ensured; long-time real-time automatic acquisition of structure health performance data of the tunnel shield can be realized; and the safety use state of the shield tunnel can be determined, and automatic safety warning can be realized.

Description

technical field [0001] The invention relates to a monitoring system, in particular to a remote monitoring system applied to the evaluation of the health state of shield tunnel structures. Background technique [0002] With the rapid development of my country's infrastructure construction, the number and scale of tunnel construction continue to expand. In the process of tunnel construction and operation, the geological conditions are relatively complex and there are many influencing factors. Structural health problems such as tunnel deformation, settlement, cracking, segment damage, and water leakage have become increasingly prominent. The automatic monitoring system for tunnel structural health has become the development of tunnel engineering. It can play a role in long-term safety monitoring and early warning of the structural state of the tunnel, and obtaining accurate and real-time monitoring data is also helpful for formulating correct structural operation and maintenanc...
