Exploration on the moistureproof measures for the tunnel of Jiaxiang seismic monitoring center station

This paper explores some measures for tunnel moistureproof by analyzing the causes of moisture in tunnels and the failures of instruments, circuits, and power supply systems due to high moisture content. These measures include waterproofing work of tunnel, the use of dehumidifier and desiccant, the daily maintenance and so on, so as to ensure the normal operation of instruments, extend the life of instruments, and reduce the failure rate.
