| 摘 要： | 利用覆盖山西蒲县地区的24景Sentinel-1A升轨影像,分别采用永久散射体雷达差分干涉测量(PS-InSAR)与短基线集雷达干涉(SBAS)技术对研究区域2019-01-2019-12的地表进行时序形变监测,获取蒲县地区疑似滑坡体位置、范围及滑坡速率,并对两种监测结果进行对比,深入分析滑坡隐患的可能性成因.结果 表明,两种时序InSAR技术采集的形变信息大致相同,蒲县大部分地区趋于稳定状态,年平均形变速率在-10 ～10mm/a;其中存在4处位置一致、形变明显的疑似滑坡点,分别是半沟村罗克线两侧、水泉窊015乡道附近、郭家山周边及井子洼村赵克路沿线.

| Abstract: | Based on 24 Sentinel-1A ascending orbit images covering the Pu County of Shanxi, PS-InSAR and SBAS technology are used to monitor the surface deformation from January 2019 to December 2019, and the location of the suspected landslides in Pu County are obtained. Range and landslide rate, and the two monitoring results are compared, in-depth analysis of the possible causes of landslide hazards. The results show that the deformation information collected by the two time-series InSAR technology is approximately the same, and most parts of Pu County tend to be stable, with an average annual deformation rate between -10mm/a~+10mm/a. Among them, four suspected landslide sites on both sides of the Rock Line of Bangou Village, near the 015 rural road of Shuiquanya, around Guojia Mountain, and along the Zhaoke Road of Jingziwa Village showed obvious deformation. |
