南水北调中线工程高填方渠道PS-InSAR形变监测
PS-InSAR Deformation Monitoring of High Fill Canal of the South-to-North Water Diversion Middle Route Project
摘要
Abstract
The South-North Water Diversion Project has played an important role in alleviating the shortage of water re-sources in the northern region and improving the local environment.As an important national instrument,ensuring its safe operation is the priority among the South-North Water Diversion Project.Using Persistent Scatterer Interferometric Synthetic Aperture Radar(PS-InSAR),from October 2016 to June 2017,the deformation monitoring was carried out on the high fill channel in Wenzhuang Village,Ye County of the Middle Route of the South-North Water Diversion Project.The results showed that the slope of about 1 km long on the east bank of the channel had obvious deformation,and the maximum shape variable reached 36mm.The longitudinal and transverse section analysis of the eastern bank of the channel and four key monitoring sections shows that the eastern bank of the channel presents an overall uneven settlement,and the closer the channel is to the water,the larger the deformation is,and the smaller the deformation is.The results of PS-InSAR monito-ring were further compared with the second-level data,and the root-mean-square error of more than 87%was less than±2 mm,and the deformation trend and magnitude were highly consistent.This research can provide reliable technical sup-port for the safety monitoring and disaster prevention of the South-North Water Diversion Project canal characterized by high fill and deep excavation.关键词
