摘要
以天津某施工区域为研究对象,开展InSAR地表形变监测研究。利用PS-InSAR技术与SBAS-InSAR技术对2017~2021年54景Sentinel-1B数据和65景Sentinel-1A数据进行处理,针对研究区地表形变时间序列,分析建筑物施工对区域地表时序变化及周边建筑物的影响。研究结果表明,沉降主要集中在研究区域两侧建筑物在建区域,抬升主要发生在研究区中间建筑物改造区域;夏季降雨期间,区域地表会出现不同程度的抬升现象。
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.
