Abstract Saige Tower in Futian District of Shenzhen City shaked abnormally on May 18, 2021. Due to the center location of the building in the city, the consequences would be unimaginable, once there was an accident. Therefore, it is of great significance to monitor the building settlement and evaluate its risk. In this paper, the authors monitored the surface deformation of Saige Tower and its surrounding areas using 29 Sentinel-1A data from May 2019 to April 2021, based on Small Baseline Subset Interferometric Synthetic Aperture Radar (SBAS-InSAR) technology. The results show that the cumulative maximum settlement of the building was -2.00 mm in August 2019, and the maximum uplift was+2.02 mm in October 2020. The overall deformation is relatively stable, and the deformation of Saige Tower fluctuates slightly within 0.4mm without settlement or uplift, especially from January 2021 to April 2021. This judgment is not only consistent with the geological conditions of the site, but also consistent with the monitoring results of multi professional institutions.

Key words： Saige Tower SBAS-InSAR settlement Sentinel-1A
