Study on Ground Subsidence in Fuzhou Geothermal Field Based on Geological Survey
Taking the geothermal field area of Fuzhou City as the research object,the ground subsidence monitoring datas were collected from November 18,2021 to November 17,2022 through leveling measurement,GNSS monitoring,and layered standard monitoring methods.The water level data of four nearby water level monitoring wells are analyzed.The results indicate that the overall land subsidence in the study area is not significant,and there is a positive correlation between land subsidence in the geothermal field area and changes in groundwater level.There are differences in the subsidence amplitude of soil layers at different depths.The deeper the soil layer,the greater the subsidence amplitude,and the greater the correlation with changes in groundwater level.
