| 摘 要： | 各大城市地下空间规划工程的建设施工，导致不同程度地面沉降的地质灾害。本文以2020年6月至2021年3月武汉市主城区的Sentinel-1A数据作为数据源，采用小基线集技术对该地区进行地表形变监测，并对其监测成果进行采样，形成时间序列形变图，通过对沉降数据对比分析，甄别出形变异常的区域，其成果可为防控地面沉降及其灾害链的发生与发展提供基础支持。

| Abstract: | Due to the construction of underground space planning projects in major cities, there are different degrees of land subsidence geological disasters. In this paper, sentinel-1A data from June 2020 to March 2021 in the main urban area of Wuhan city is selected as the data source, and the small baseline set technology is used to monitor the surface deformation in this area. The results can provide basic support for the prevention and control of land subsidence and the occurrence and development of disaster chain. |
