摘要
针对城市地面沉降现状,以贵阳市为研究区,以2019-2021年72期C波段的Sentinel-1A卫星影像为数据源,利用SNAP-STaMPS处理链开展了城市地表的形变监测,获取了研究区的地表形变信息。结果表明:贵阳市沉降主要发生在西北部区域,中心城区有抬升的趋势,沉降区域零散分布在北部区域;东部地区整体较为稳定,在龙洞堡机场区域探测到明显的沉降现象,可为规划建设、城市地质安全以及沉降防控等提供参考。
For the current situation of urban land subsidence,in this paper,taking Guiyang City as the research area and Sentinel-1A satellite images in the C-band of the 72nd phase from 2019 to 2021 as the data source,the SNAP-STaMPS processing chain was used to monitor the deformation of the urban surface and obtain the deformation information of the study area.The results show that the settlement of Guiyang City mainly occurs in the northwest area;the central urban area has a tendency to rise,and the settlement area is scattered in the northern area.The eastern region is relatively stable as a whole,and obvious settlement phenomena have been detected in the Longdongbao airport area,which can provide a reference for planning and construction,urban geological safety,and settlement prevention and control.
