| 摘 要： | 采用3类InSAR产品和DEM数据开展金沙江流域乌东德水电站段的潜在滑坡探测，成功识别出多处已知和未知的滑坡点，并探测出滑坡体的形态及稳定性，提供了一种高效的大范围滑坡探测技术。同时采用小基线集InSAR技术对金坪子滑坡进行监测，不仅获得该滑坡的空间分区特征，也获取重点滑坡区的时间序列结果，并且与地面监测结果比较，精度达1.8 cm。展示了不同InSAR技术在不同尺度滑坡调查与监测中的应用特点。

| Abstract: | Three InSAR products and DEM data are involved in detecting potential landslides over Wudongde Hydropower station section, Jinshajiang. Several known and unknown landslides are successfully detected, and their spatial patterns and stabilities are detected, showing that this procedure is an efficient means to detect active landslides in a large area. Meanwhile, small baseline subsets InSAR technique is applied to monitor the Jinpingzi landslide. Both spatial zonation features and time-series deformation results in key landslide zone are achieved. The InSAR precision in slide direction is 1.8 cm by comparing with in-situ total station measurements. Different InSAR techniques are illustrated in this paper for different scale landslide applications. |
