基于CORS网监测台州地区陆地水负荷对地表垂直形变的影响

Monitoring of Surface Vertical Deformation from Terrestrial Water Loading in Taizhou Region by the CORS Network

基于CORS站网基线综合解算,利用移去-恢复法和负荷形变法监测陆地水负荷对地表垂直形变的影响。以台州地区为例,对2017~2019年CORS站网和相关区域负荷数据进行分析。结果表明,台州地区陆地水负荷对地表垂直形变的影响存在季节性变化,地下水负荷影响较为明显,可达cm级;且该影响在年际尺度上相对稳定。利用CORS站网可以监测陆地水负荷引起的地表垂直形变,为水动力环境监测与地质灾害监测提供参考。

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.
