基于PS-InSAR技术的墨西哥城区地面形变监测研究
Research on Surface Deformation Monitoring Method in Mexico Urban Areas Based on PS-InSAR Technology
摘要
Abstract
Surface subsidence has become an important issue facing the rapid development of super large cities.Traditional monitoring methods with low spatio-temporal resolution,and InSAR as a new type of monitoring method,has been rapidly developed and applied.In this study,we used InSAR to carry out high-precision deformation monitoring in urban areas of Mexico,obtained deformation rate maps and cumulative deformation maps from 2020 to 2022,and conducted thematic analysis of key areas and typical sites to provide data support for scientific decision-making.The results show that during October 2020 to October 2022,the overall deformation of study area is obvious.The areas with large deformation rate/deformation amount include Iztapalapa,Cuauhtémoc,RAUL ROMERO,BOSQUES DE ARAGON,etc.The minimum deformation rate/cumulative deformation is located in the central area of Nezahualcóyotl,with LOS deformation rate of-302.1 mm/a and cumulative deformation of-575.3 mm.At the same time,we conducted a deformation prediction for some areas for 120 days.The prediction results showed that the deformation range was-600~100 mm.关键词
