Abstract:Based on the comprehensive calculation of CORS network baseline, we use the removal recovery and load deformation methods to monitor the influence of the terrestrial water loading on surface vertical deformation. Taking the Taizhou area as an example, the loading data of CORS network and related regional data from 2017 to 2019 are analyzed. The results show that the influence of terrestrial water loading on surface vertical deformation varies seasonally, and the groundwater loading influence is obvious, which can reach the centimeter level. The influence of terrestrial water loading on vertical deformation in Taizhou area is relatively stable on an interannual scale. The CORS network can monitor the surface vertical deformation caused by terrestrial water loading and can provide important reference for hydrodynamic environmental monitoring and geological disaster monitoring.
