Design and Application of Multidimensional Monitoring and Early Warning System for Tunnel Safety

The tunnel project has a large one-time investment, a long construction period, and potential safety hazards. During the operation period, structural cracks, voids, deformation, dislocation, water leakage and other diseases may occur, which greatly reduces the use function of the tunnel and threatens its safety in construction and operation. Therefore, it is necessary to carry out the development and research of tunnel safety monitoring and early warning system to pre-perceive and predict the working state and disease characteristics of the tunnel structure and timely warn. Aiming at the working state and disease characteristics of the tunnel, this paper discusses how to obtain the dynamic changes of the working state and disease characteristics of the key parts of the tunnel in real time, and optimizes the design of the tunnel safety monitoring and early warning system. A multi-dimensional monitoring and early warning system for tunnel safety is recommended, which can control the working state and disease changes of the tunnel in real time, and improve the service quality and service life of the tunnel.
