某水电站解放沟左岸反倾高边坡蓄水稳定性分析

主要研究了在水库蓄水后某一反倾高边坡的稳定性问题。采用FLAC3D软件计算和分析不同蓄水位下的边坡稳定性，得到较理想的结果。结果表明，蓄水条件下边坡的整体稳定性，主要是变形稳定性问题；按解放沟左岸边坡实际的风化状态进行赋值，在任何蓄水位下，边坡整体上是稳定的；边坡在蓄水条件下的整体稳定性对岩体力学参数比较敏感；边坡整体是稳定的。

Stability analysis of left high slope at Jiefanggou under the condition of storing water for a certain hydropower station

The paper studies the problem of a high steep slope stability under the condition of storing water. The problem is analyzed and computed under the conditions of different storing water levels by FLAC3D software. From the results obtained we draw some conclusions: The stability of whole slope under the condition of storing water, is mainly related to the deformation stability. When the parameters determining with the fact of weathering, the productions of simulation indicated that the whole slope is stable at any water levels. The calculation of parameter sensitivity indicates that the whole slope’s stability is sensitive to rock mass parameters under condition of storing water. The whole slope is stable.
