摘要
以海原断裂带为研究区,开展了基于2015年3月~2016年7月的20景哨兵一号(Sentinel-1)数据和SBAS-InSAR技术的时序断裂带形变监测。结果表明,研究区形变累积量集中在-10^+5mm,海原县第一中学附近存在明显沉降漏斗,其沉降累积量达28mm;海原断裂带南北两盘相对形变速率约为6mm/a,运动性质为左旋走滑,与GPS和地质学研究结果基本一致。
In this paper, taking the fault zone of Haiyuan as the study area, we carried out the time-series deformation monitoring of the fault zone based on 20 scenes of Sentinel-1 data and SBAS-InSAR technology. The results show that the cumulative deformation of this study area is about-10^+5 mm. The maximum cumulative land subsidence is about 28 mm, which locates near No.1 Middle School of Haiyuan County. The fault zone of Haiyuan displays a left lateral slip, the relative rate is about 6 mm/a, which is roughly in agreement with that from GPS and geological investigations.
