国产 GB-InSAR 在特大型水库滑坡变形监测中的应用

The stability of large-scale landslide in the reservoir area of hydropower station has an important impact on the safety of dam structure and surrounding people's life and property. Large-scale real-time accurate observation of the stability and deformation trend of this type of landslide can provide reliable early warning and control information for the landslide, which is of great significance. The traditional monitoring methods of landslide in the reservoir area of hydropower station are mainly GNSS monitoring and total station monitoring. In this study, the advanced GB-InSAR system LKR-05-KU-S100 is applied to the monitoring of Cangjiangqiao-Yingpan landslide and Dahua landslide of Dahuaqiao hydropower station on Lancang River. Field monitoring tests show that the system has high precision, and it can carry out long-distance, all-day, all-weather, and large-scale monitoring. It has unique advantages and broad application prospects for the monitoring of large and super-large landslides.
