InSAR技术在高速铁路采空区地质选线中的应用研究

随着高速铁路的快速发展,铁路选线不可避免地将会穿越采空区,需要准确查明采空区的分布和影响范围。文中使用InSAR(合成孔径雷达干涉测量)技术,通过2009~2015年间的数据对比分析,查明某在建高铁跨越采空区的分布和影响范围,为线位的选择提供指导。结果表明,InSAR是一种有效的采空区变形监测技术,在铁路跨越采空区变形分析及指导地质选线中具有广阔的应用前景。

Application of InSAR in Geological Alignment of High-Speed Railway in Goaf

With the rapid development of high-speed railway,it is inevitable that the high-speed railway passes though the goaf,which requires the identification of the distribution and influence sphere of the goaf. The paper employs InSAR(Interferometric Synthetic Aperture Radar) to analyze the data of 2009 ~2015 to find out the distribution and influence sphere of the goaf and provide guidance for railway alignment. The results show that InSAR is an effective technology in goaf deformation detection and will see wide application in future.
