PS-InSAR技术在凉水河通州段堤防与水闸沉降监测中的应用分析
Application analysis based on PS-InSAR technology in the monitoring of levee and sluice settlement monitoring of Liangshui River
摘要
Abstract
The precipitation in flood season accounts for 85%of the annual precipitation in Beijing.Pre-cipitation and flood are significant factors threatening the safety of sluice and dike,leading to potential hazardous situations at their junctions.Based on PS-InSAR technology,three large sluices and their adja-cent levees in Tongzhou section of Liangshui River were monitored,and the average settlement rate and cumulative vertical displacement of sluices and adjacent levees in flood season were analyzed.The results show that the maximum cumulative displacement of levee is 50.20 mm,and the maximum cumulative dis-placement of sluice is 45.30 mm.The study area is in the overall settlement state,and the settlement de-formation trend of levee and sluice is basically the same,and the regional settlement is the main reason.GNSS is used as an auxiliary means to verify the accuracy of PS-InSAR measurement points.The vertical displacement trends of sluice and dike are basically the same.PS-InSAR technology can be used as an auxiliary technology to monitor the settlement of hydraulic structures such as sluice and dike.关键词
