摘要
为了快速准确对太原市地面沉降进行监测和有效管理,基于2016年2月17日至2018年2月18日的20景Sentinel-1A影像,采用PS-DInSAR技术对太原市地面沉降进行了监测。结果表明:太原市的主要沉降区域为小店区、吴家堡、北固碾村、杨家峪和西张,且以小店区的地面沉降最为严重;太原市地面沉降速率呈先增大后减弱趋势;田庄断层对小店区地面沉降规律具有显著影响。与前人研究和太原市水井点的对比表明,基于PS-DInSAR技术对太原市地面沉降进行监测的结果可以满足实际的监测和管理需求。
In order to accurately monitor and effectively manage the ground subsidence in Taiyuan city of Shanxi province,China,PS-DInSAR method was adopted to monitor the ground surface subsidence based on the 20 scenes Sentinel-1A image between February 17,2016 and February 18,2018.The monitoring results showed that the main subsidence areas in Taiyuan city were located in Xiaodian,Wujiabao,Beigunian,Yangjiayu and Xizhang.And the most serious ground settlement occurred in the Xiaodian.During the past two years,the ground subsidence rate in Taiyuan city firstly increased and then decreased.Tianzhuang fault had played a significant role in the ground subsidence rule in Xiaodian.Compared with previous studies and wells in Taiyuan city,the results of ground subsidence in Taiyuan city based on PS-DInSAR method could meet the monitoring and management needs.
