摘要
有效监测水利工程的安全稳定至关重要,合成孔径雷达干涉测量(Interferometric Synthetic Aperture Radar,InSAR)技术具有全天时、全天候、高精度和低成本等优点,已在水利工程中得到了广泛应用。介绍InSAR技术监测地表形变的基本原理和当前常用的SAR影像基本参数,综述近年来InSAR技术在水利工程形变监测应用方面的研究现状和进展,并探讨InSAR技术在长江沿线大型线状堤防工程稳定性监测应用中存在的问题。随着SAR卫星系统的不断发展,InSAR技术能够获取更加精细准确的形变信息,其在水利工程形变监测方面的应用会更加成熟、广泛。
Effective monitoring is of vital importance in the water conservancy project safety and stability.Interferometric Synthetic Aperture Radar technology has the advantages of all-day,all-weather,high-precision and low-cost.It has been widely used in water conservancy projects.Firstly,the basic principle of InSAR technology for monitoring surface deformation and the basic parameters of SAR images in common use are introduced.The research status and progress of InSAR technology in monitoring deformation of water conservancy project in recent ten years are reviewed,and several problems existing in the application of InSAR technology in monitoring stability of large linear dikes along the Yangtze River are discussed.With the continuous development of SAR satellite system,InSAR technology can obtain more precise and accurate deformation information,and its application in deformation monitoring of linear water conservancy project will be more mature and more extensive.
