摘要
文中利用20景Sentinel1A影像,采用PS-InSAR技术对唐山市曹妃甸区填海区域进行地表形变监测,得到了该研究区域的年平均沉降速率及累积沉降量等地表形变结果。结果显示:该区域最大的年平均沉降速率达到了-26.55 876 mm/a,最大的总累积沉降量为-379.439 358 mm,主要是靠近海域位置的地表沉降。
In this paper,20 Sentinel1 Aimages were used to monitor the surface deformation of reclamation area in Caofeidian in Tangshan City by using PS-InSAR technology. The results of the annual average settlement rate and cumulative settlement in the study area were obtained. The results showed that the maximum annual average settlement rate was-26. 558 76 mm/a,and the maximum total cumulative settlement was-379. 439 358 mm,it was mainly the surface settlement near the sea area.
