摘　　要：固结灌浆可以有效地提高岩体的强度、完整性及渗透性能,白衣河水库工程泄洪输水隧洞围岩破碎,抗渗性能较差,围岩条件不能满足规范要求,因此需采用固结灌浆提高围岩的抗渗性能。通过对白衣河水库工程泄洪输水隧洞围岩灌浆压水试验和平均单位耗灰量成果进行分析可以得出:固结灌浆可有效提高围岩的抗渗指标。Consolidation grouting can effectively improve the strength,integrity,and permeability of rock masses.The surrounding rock offlood discharge and water conveyance tunnel of Baiyihe Reservoir project is broken,with poor impermeability,and the surrounding rock conditions cannot meet the standard requirements.Therefore,it is necessary to use consolidation grouting to improve the impermeability ofsurrounding rock.Through the analysis of grouting pressure test and average unit ash consumption results of surrounding rock of Baiyihe Reservoir project's flood discharge and water conveyance tunnel,it can be concluded that consolidation grouting can effectively improve the impermeability index of surrounding rock.
