Surface Deformation Monitoring of Construction Area Based on InSAR Technology
Abstract Using a construction area in Tianjin as the research object, we carry out research on InSAR surface deformation monitoring. We use PS-InSAR technology and SBAS-InSAR technology to process 54 sentinel-1b data and 65 sentinel-1a data from 2017 to 2021. We analyze the time series changes of the surface in the area due to the construction of buildings and the impact on the surrounding buildings. The results show that compared with precision leveling, the settlement of the study area is mainly concentrated around buildings under construction on both sides of the study area, and the lifting area is mainly in the building reconstruction area in the middle of the study area. During summer rainfall, the surface of the region will rise to varying degrees.
