基于小基线集InSAR的杭州市地铁沿线地表移动变形监测
Surface Movement and Deformation Monitoring Along Hangzhou Subway Based on SBAS Interferometry
摘要
Abstract
Subsidence deformation monitoring of large urban transportation systems is one of the significant steps to ensure safe operation.Considering the situation of subsidence in Hangzhoudong Station,this study utilizes Sentinel-1 microwave imagery from July 2015 to December 2023 and applies the Small Baseline Subset Interferometric Synthetic Aperture Radar(SBAS-InSAR)method to monitor surface deformation along Hangzhou subway.The results indicate that the surface movement and deformation along with Hangzhou subway lines exhibits significant spatiotemporal differentiation,where the western and northern areas are less than that of other directions and slightly dispersed.However,the southern areas,including Xiaoshan and Jianggan,show more pronounced and widespread subsidence.Notably,in the southeastern area of Xiaoshan District,subsidence is extensive,with a maximum subsidence rate of-86.625 mm/year,and a maximum uplift rate of 25.024 mm/year.Additionally,24.81%of the areas of Hangzhou subway lines have significant subsidence characteristics.关键词
