摘要
本文利用Sentinel-1A SAR影像,通过小基线集(SBAS-InSAR)技术获取了马村区2016年10月26日至2019年3月9日地面沉降的年平均形变速率。监测结果表明,由于土地整治政策、人工开采以及矿区长期排水等因素的影响,马村区内存在多个沉降中心,其中最大沉降量达到-200 mm,最大形变速率达到-88 mm/a。通过建立剖面,提取并分析了张白河村、亮马村和新村附近沉降中心的沉降现状。
In this paper, the Sentinel-1A SAR images are used to obtain the average annual deformation rate and ofland subsidence from December 26, 2016 to March 9, 2016 in the Macun district by using small baseline InSAR technique. The monitoring results show that, due to land regulation policies, artificial mining and long-term drainage, there are multiple settlement centers in the area, among which the maximum settlement amount reaches negative 200 mm and the maximum deformation rate reaches negative 88 mm/a. Through the establishment of profile, the settlement status of the settlement center near Zhangbaihe village, Liangma village and Xincun village are extracted and analyzed.
