本文研究了蓄水条件下高陡边坡的稳定性问题。利用FLAC3D软件对不同蓄水位条件下的问题进行了分析和计算。结果表明：蓄水条件下边坡整体稳定性主要与变形稳定性有关。当参数随风化实际确定时，模拟结果表明，在任何水位下，整个边坡都是稳定的。参数敏感性计算表明，在蓄水条件下，边坡整体稳定性对岩体参数比较敏感。整个斜坡是稳定的。
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.
