摘　　要：针对常规测量手段耗时、费力,难以快速完成大型交通设施的形变监测的问题,该文开展了基于高空间分辨率SAR影像的PS-InSAR在大型交通设施形变监测方面的实验研究:选取2009—2010年间27景3m分辨率的TerraSAR-X数据,采用PS-InSAR技术提取了天津市西部城郊结合区内主要交通设施及沿线区域的地表形变信息。结果表明:利用高分辨率SAR影像监测公路、铁路等交通设施时,可以提取高密度的PS监测点;提取形变信息与水准观测值相互吻合;研究区域存在几个较大的沉降中心,使得一些交通设施在部分路段沉降较大。Aiming at the problem that conventional survey methods are time-consuming and laborious,difficult to quickly complete the deformation monitoring on large transport infrastructure,this paper studied on large transport Infrastructures deformation monitoring using PS-InSAR based on high resolution SAR Images：a dataset of 27 scenes 3mresolution TerraSAR-X data acquired between 2009 to 2010was selected to extract the surface deformation information of the area along the the main traffic trunk line in Tianjin west edge based on PS-InSAR technology.Results demonstrated that：high-resolution SAR images could be used to monitor road,rail and other transportation facilities,and the derived deformation showed good agreement with the leveling data;moreover,there existed several large centers of subsidence in the study area,subjecting some transport facilities to larger subsidence.
