摘要: 本文首先利用小基线集时序InSAR(SBAS-InSAR)技术对云南省宣威东北部地表进行形变监测,获取2021年1月至2023年6月的形变结果;然后分析选取的典型滑坡的形变特征,采集了GNSS监测数据与InSAR形变监测进行对比验证;最后分析InSAR形变对降雨的响应。研究结果表明,SBAS-InSAR技术能有效监测西南山区的典型滑坡,该结果可为滑坡灾害的早期识别提供支撑,对于同类型滑坡灾害的稳定性监测具有较高的参考价值。

Abstract: In this study, the small baseline subset time-series InSAR (SBAS-InSAR) technique is employed to monitor surface deformation in the northeastern part of Xuanwei, Yunnan province. Deformation results from January 2021 to June 2023 are obtained, and the deformation characteristics of the selected typical landslide are analyzed. GNSS monitoring data are collected and compared with the InSAR deformation monitoring for validation. Furthermore, the response of InSAR deformation to precipitation is analyzed. The research findings demonstrate the effectiveness of SBAS-InSAR in monitoring typical landslide in the southwestern mountainous regions. These results offer support for the early identification of landslide hazards and hold significant reference value for the stability monitoring of similar landslide disasters.

Key words: landslide, SBAS-InSAR, stability monitoring, precipitation response
