基于星载时序InSAR的长距离输水管线健康监测
Long Distance Water Transmission Pipeline Health Monitoring Based on Satellite-borne Time-series InSAR
摘要
Abstract
Long distance water transmission pipeline is an important part of water resources allocation project,which plays an important role in real-izing the rational allocation of water resources in our country.It is very important for the safe operation of water conveyance project to monitor the surface deformation around the pipeline.Using satellite-borne time-series synthetic aperture radar interferometry technique(MT-InSAR)can obtain the surface deformation information along the pipeline over a large area efficiently,which is helpful to detect potential geological hazards.In this paper,we used the temporal subset time-series SBAS-InSAR method based on natural years to process Sentinel-1 data,and obtained the surface deformation along the B2 section of the Pearl River Delta water resources allocation project in 2021 and 2022.By analyzing the changes of surface deformation along the B2 section during the two-year period,we found that there were 6 areas with aggravated surface deformation along the B2 section from 2021 to 2022,which would bring potential geological risks to the safe construction and operation of water transmission pipeline.关键词
