Abstract: According to the geological conditions of the right bank slope of Ertan hydropower station, the area of slope collapse and sliding is divided, the failure mechanism of slope collapse and sliding is analyzed in depth, the effective and feasible treatment scheme is discussed comprehensively, and protective measures are taken accordingly. The practice shows that the slope collapse and sliding control in atomized area is very successful, and no collapse happen again.

Key words: slope, deformation, treatment

摘要： 根据二滩水电站右岸边坡地质条件，对边坡塌滑变形区域进行划分，深入分析塌滑变形破坏机理，综合探讨有效、可行的治理方案，有针对性地采取防护治理措施。实践表明，雾化区边坡治理非常成功，再未发生塌滑情况。
