星载InSAR在某研究区滑坡体变形监测中的应用

Application of Spaceborne InSAR about Landslide Deformation Monitoring in a Study Area

在某研究区将星载InSAR技术应用于滑坡体变形监测中,实现了滑坡体面域监测,并能追溯滑坡体历史变形,通过与点式监测成果对比,监测成果一致性较好,解决了滑坡体历史形变无法追溯、点式监测危险部位无法布点不能大范围监测的问题;结合深部变形监测实现了滑坡体点线面体的全方位监控;同时研究区大范围的星载InSAR监测成功识别出未开展点式监测区域的滑坡体缓慢变形状态,对滑坡识别与监控滑坡安全发挥了重要作用。

The spaceborne InSAR technique was used for deformation monitoring of landslide body in a study area, the area monitoring was realized,and the history deformation of landslide can be traced. By comparing the results with point-based monitoring results, the results were in good coincidence. The problems about the historical deformation of landslide body cannot be traced and point monitoring can’t put in dangerous parts or can’t monitoring for wide range were solved. Combined with the deep deformation monitoring, the comprehensive monitoring of landslide in point class, line class, area class, volume class were realized. At the same time, a largescale spaceborne InSAR monitoring in the study area successfully identified the slow deformation of landslide which in the unmonitored area, it has played an important role about monitoring landslide safety and landslide recognition.
