摘　　要：运用正交试验设计方法,采用Ⅱ级粉煤灰,优选出高性能粉煤灰混凝土配合比(粉煤灰25%,水胶比为0.31,抗渗等级W37,抗冻等级F300),应用于黑河龙首二级水电站混凝土面板坝工程中。满足面板混凝土高耐久性的要求,并有效地控制了裂缝的产生。High performance fly ash concrete （cement volume 25 %, ratio of water to binder 0.31, W37, F300） was selected by orthogonal experimental design method with grade- Ⅱ fly ash. The concrete was succeeded in applying to CFRD of Longshou secondary hydropower station of Hei River of Gansu. The high durability of face concrete was satisfied and the cracks of concrete were reduced efficiently.
