| 摘 要： | 针对水库蓄水前后和库水位骤降等均会影响库岸边坡稳定性的问题,以十里铺水电站为例,根据地质资料,选取近库的、规模较大的水草坪滑坡体建立了计算模型,分析了水库蓄水前后和库水位骤降情况下该滑坡体的稳定性。结果表明,水库蓄水前水草坪滑坡体整体基本稳定,坡体上部局部失稳的可能性较大,水库蓄水后滑坡体稳定性下降,库水位骤降时将产生坡脚塌岸现象,并引发坡体上部失稳。

| Abstract: | According to the fact that reservoir impoundment and water level sudden fall have impact of bank slopes stability, Shilipu Hydropower Station is taken for an example. The large Shuicaoping landslide mass near reservoir is selected to establish computing model based on geologic data. The landslide stability is analyzed in conditions of before and after impoundment and reservoir water level sudden fall. The results show that the Shuicaoping landslide mass is stable globally; the upper part has possibility of local instability; the stability of the landslide decreases under reservoir storage; bank collapse will occur at toe of slope due to sudden water level fall; furthermore, it will induce the destabilization of the upper part landslide. |
