Abstract:
北京地区地表不均匀沉降较为严重,为保证桥梁结构安全,有必要对地表沉降变形较严重区域的桥梁沉降变形进行监测.永久散射体合成孔径雷达干涉测量(Persistent Scatterer-Interferometric Synthetic Aperture Radar,PS-InSAR)技术用于桥梁沉降变形监测具有大尺度、分辨率高等特点,同传统方法相比有其优越性.利用TerraSAR-X遥感卫星的SAR影像对桥梁进行沉降变形监测,提取桥梁及附近周围反射明显的PS点,采用PS-InSAR技术对桥梁沉降变形进行研究,研究成果对于PS-InSAR技术用于桥梁变形监测具有一定的参考意义.
