黄河上游某电站^#1滑坡运动特征分析

Analysis on motion feature of the No.1 landslide at a hydropower station on Yellow River

为分析黄河上游某电站#1滑坡的运动特征,详细论述了滑坡区地质环境、滑坡体的堆积特征,并阐述了滑坡形成的机制.通过地貌对比与分析,对滑坡发生前的原始地形地貌形态进行了恢复,采用离散单元法对滑坡运动过程进行了计算机模拟,模拟结果揭示了#1滑坡的形成机制及其运动特征,表明#1滑坡形成时滑速较大,与实际调查结果非常吻合.

In order to analyze the motion feature of the No.1 landslide at a hydropower station on Yellow River, geologic condition of the landslide area and the feature of the landslide deposit are expounded in detail, and then the formation mechanism of the landslide is discussed as well. By comparison and analysis on the land form therein, the original land form before the landslide is restored, while the formation mechanism and motion attribute of the landslide are simulated with DEM; of which the result shows that the creating speed of the landslide is higher, that coincides with that of the site investigation basically.
