Multi-platform InSAR Three-Dimensional Deformation Monitoring of Henan Changge Section of South-to-North Water Diversion Project
摘要
Abstract
[Objective]To ensure the safe operation of the Middle Route of South-to-North Water Diversion Project,it is necessary to monitor channel surface deformation.[Methods]Based on 74 Sentinel-1A images from December 2019 to December 2020,SBAS-InSAR technology was applied to conduct a comprehensive survey of deformation in Henan section of South-to-North Water Diversion Project.Additionally,15 ascending and 15 descending TerraSAR-X images were integrated using DS-InSAR technology for precise multi-platform InSAR detection of three-dimensional deformation in Henan Changge section.[Results]Twenty-two significant deformation zones were identified along Henan section,with a maximum deforma-tion rate of-98 mm/year.Notably,a 1.6 km channel segment in Changge exhibited excessive settlement.Settlement funnels were observed in the channel near Shuimohe Village and Kuncheng Coal Mine in Yuzhou,with peak deformation rates reac-hing-26 mm/year and-40 mm/year,respectively.The former showed only vertical deformation,while the latter displayed both vertical and east-west bidirectional deformation.[Conclusion]Verification against second-order leveling data confirms that vertical deformation of the channel near Shuimohe Village aligns closely with leveling trends,with a maximum error of±2 mm,indicating reliable accuracy.This provides theoretical and technical support for the application of InSAR three-dimensional deformation monitoring in disaster early warning and prevention in hydraulic engineering.关键词
