摘要
利用2014-2018年覆盖南昌市区域范围Sentinel-1A卫星数据,采用PS-InSAR技术对南昌市主要的基础设施建设,如高铁、地铁、隧道、桥梁、高楼等地表形变情况进行计算、趋势分析与及时监测,为区域灾害提供预警与评估,及为地区规划与发展提供决策支持。PS-InSAR技术在地面沉降、自然灾害等地表形变监测方面已得到广泛的应用。就PS-InSAR在南昌地表形变监测的应用进行了探讨,并根据InSAR的特点,指出了InSAR的部分缺陷,给出了InSAR的使用局限以及今后的研究方向。
Urban land subsidence monitoring is of great significance to urban safety and development.Based on Sentinel-1A satellite data covering the urban area of Nanchang from 2014 to 2018,this paper uses PS-InSAR technology to calculate,trend analysis and timely monitoring the surface deformation of major infrastructure construction in Nanchang,such as high-speed railway,subway,tunnel,bridge and high-rise buildings,in order to provide early warning and assessment for regional disaster prediction,and Regional planning and development provide decision support.PS-InSAR technology has been widely used in monitoring land subsidence and natural disasters.In this paper,the application of PS-InSAR in deformation monitoring is discussed.According to the characteristics of InSAR,some shortcomings of InSAR are pointed out,and the limitations of InSAR and future research directions are given.
