Abstract:Combining with actual situation of ground subsidence in Jining urban area, on the basis of fully considering the needs of realtime monitoring, fine monitoring and emergency monitoring, a land subsidence monitoring system, including monitoring station, leveling monitoring network and GNSS monitoring network has been designed. The construction scheme of multifunctional integrated monitoring station for ground subsidence has been put forward. The data center, monitoring standard group, groundwater monitoring, GNSS continuous operation (bedrock) reference station, popular science publicity, security and other functions are integrated. It can be shared and utilized in the fields of site, equipment, power network and infrastructure, which will greatly improve the utilization efficiency of land subsidence monitoring facilities. The monitoring standard group includes bench mark, delamination mark, water level observation hole, pore water pressure observation hole and data acquisition equipment. In order to facilitate the collection, reception, storage, processing and display of data, a comprehensive land subsidence monitoring and management system has been established on the server in the mode of "data center + monitoring station". Monitoring facilities, publicity films, exhibition boards and other activities should be fully used to carry out popular science publicity and education activities of land subsidence prevention and control. Within the scope of the districts in Jining city, land subsidence monitoring network is constructed by using leveling points and GNSS monitoring points.
