| Abstract: | In this paper,a total of 32 scenes of Sentinel-1 ascending orbit image data from December 2018 to December 2019 were selected,and the deformation information was extracted from Guiyang based on PSI technology.The results shown that a total of 24 large deformation areas were found in the monitoring area,including 21 settlement areas and 3 elevation areas.Through statistical methods,it was proved that there was no obvious deformation along the subway line.Analysis of the deformation zones shown that 24 deformation zones were all related to urbanization construction and had no relation to subway construction operation.Finally,it selected 3 places from the deformation zone as examples for analysis,and analyzed the reasons.The research results of this paper provided reference for relevant departments to carry out survey on surface deformation and settlement monitoring,as the theoretical basis for urban safety monitoring. |
