- Abstract:
- Based on the background of the Nanchang Honggu Tunnel, which is the largest inland river immersed tunnel to date in China, some research work on the construction of the Nanchang Honggu Tunnel health monitoring and assessment system is introduced. The platform of the health monitoring and assessment system is established with a relatively mature structure, including the sensor subsystem, data acquisition subsystem, data transmission subsystem, database subsystem, data processing and control subsystem, and health assessment and pre-warning subsystem. Monitoring index selection, sensor selection and sensor layout are fully considered in the health monitoring design and technology scheme. The fuzzy-AHP(analytic hierarchy process)evaluation method is employed to establish the Honggu Tunnel health assessment model, and the index weight determination method and grading control criterion are investigated and given. Then, the functions of the software system are achieved with advanced cloud platform technology, and the running costs of the system is reduced greatly. In summary, the establishment of the Nanchang Honggu Tunnel health monitoring and assessment system is described and such a system can realize real-time monitoring of the Honggu Tunnel and make it more convenient for implementing health assessment, pre-warning, and some other functions. Managers can operate the system using PCs and cell phones. At the same time, the relevant work on this system can provide a good reference for other immersed tunnels.
