摘　　要：通过对龙滩水电站蠕变岩体非开挖区边坡变形机制和倾倒破坏模式的分析与计算,对蠕变岩体非开挖区边坡自然状态及受施工道路开挖影响条件下的稳定性进行了综合评价,并对边坡在水库蓄水过程中和运行期可能产生的变形破坏方式及稳定性进行了预测。This paper briefs the deformation mechanism and inversion collapse mode of the non-excavated slope with creeping rock mass, and based on the analysis and computation , assesses the natural status of the non-excavated slope with creeping rock mass and its stability under the condition of the excavation of the construction access road, and predicts the the potential deformation failure mode and the stability of the slope during the impoundment and operation of the reservoir.
