基于时序InSAR的南水北调中线暗埋段地表沉降分析
Surface Subsidence Analysis of Buried Section of Middle Line of the South-to-North Water Transfer Project Based on Time Series InSAR
摘要
Abstract
In this paper,we used the interferometric synthetic aperture radar(InSAR)technology to study the surface subsidence of buried section from Baoding to Tianjin of the South-to-North Water Transfer Project.Based on Sentinel-1 data,we used three algorithms,such as Stacking-InSAR,SBAS-InSAR,DS-InSAR to obtain the deformation results of study area.Then,we analyzed the characteristics by comparing the results of three algorithms,which could prove the effect of InSAR in the surface subsidence monitoring of buried section of the South-to-North Water Transfer Project.By analyzing the deformation characteristics of study area,we found two obvious subsidence funnel sections and one transient surface uplift section.The deformation funnels were related to groundwater overexploitation and soil compaction caused by buildings,while the surface uplift was related to the sudden increase in local precipitation.关键词
