摘　　要：为研究水库库岸滑坡的稳定性对水库正常蓄水及安全运行的重要性,在分析白龙江碧口水电站河口滑坡所处的环境条件、滑坡变形破坏特征等基础上,采用定性与定量计算方法分析了水库蓄水前后及达到淤排平衡等不同条件下的稳定性变化情况,尤其水库游积对滑坡稳定性的作用。计算结果与实际相符,说明水库淤积对滑坡稳定性有益。In order to study the stability of reservoir bank landslide and its importance to the impoundment and safe operation of reservoir, based on the analysis of environmental conditions and characteristics of deformation and failure in Hekou landslide of Bikou Hydropower Station in Pailong River, the qualitative and quantitative calculation methods are used to analyze the change of stability under different conditions, such as before and after impounding and silt row bal- ance, especially the effect of reservoir sedimentation on landslide stability. The calculation result is consistent with the ac- tual and it shows that reservoir sedimentation is beneficial to the stability of the landslide.
