| Summary: | This paper, obtaining 39scenesof images of the Sentinel-1 A/B, monitored the Cangzhou area subsidence from Mar.
2015 to Dec. 2016 basing on using PS-InSAR technique. The annual average subsidence rate and accumulative
subsidence were obtained. The results showed that the ground surface of Xian County,Cang County, Cangzhou
urban area had a rebound trend; Qing County, the east of Cang County ,the west of Nanpi County and Dongguang
County appeared obvious subsidence, and the accumulated subsidence in Hezhuang village of Dongguang County
reached 47 mm. And from that the main reason leading to these obvious subsidence was over-exploitation of ground-water. At last, it analyzed the settlement of the High-Speed Railway (HR) which was north from the Machang
town of QingCounty and south to the Lian town of Dongguang County in Cangzhou.The relative deformation of
the HR between the two sections which was Lierzhuang village of Cang County and Chenxin village of Nanpi
County arrived at 30 mm. Moreover, this paper discussed the application of Sentinel-1 A/B SAR images in
monitoring urban land subsidence and the results provided important basic data for the relevant
departments. |
