Abstract

To conduct an investigation on the deformation of the Shuangwangcheng Reservoir, this study employed the full-resolution time-series InSAR method to analyze the Sentinel-1 ascending and descending track data from July 2015 to July 2023. The investigation unveiled substantial subsidence in the reservoir dam, exhibiting deformation rates varying from -15 mm/year to -30 mm/year. Notably, a disparity in subsidence rates was observed between the eastern and western sides of the reservoir. Subsequently, the SBAS-InSAR method was employed to monitor the deformation of the surrounding area of the reservoir. It was revealed that the differential deformation rate of the dam may be attributed to the extraction of underground brine from the salt field located on the eastern side of the reservoir.
