摘　　要：结合黄金坪水电站导流洞塌方段的地质条件和围岩岩体特征,分析了塌方原因。简述了对塌方段围岩实施的固结灌浆处理措施,并依据监测结果对处理效果进行了评价。塌方段围岩在固结灌浆处理后处于稳定状态,证明了该处理措施的有效性和可行性。geological conditions and characteristics of the surrounding rock of diversion tunnel collapse in Huangjinping Hydropower Station are combined to analyze the collapse reason. Consolidation grouting measures implemented on surrounding rock of the collapse segment are introduced, and the treatment effect is evaluated in accordance with the monitoring results. The surrounding rock in the collapse segment is in the stable state after consolidation grouting treatment, thereby providing the effectiveness and feasibility of the measures.
