摘　　要：鉴于龚嘴水电站运行发电已30余年,在第三轮定期检查中,得知7号溢洪道左侧导墙被高速水流淘刷出长约13 m、高约3 m、最深处约3 m的深坑,已经威胁到溢洪道及临近的6号冲砂底孔的安全运行,介绍了龚嘴大坝7号溢洪道左侧导墙水下冲蚀破坏部分采用水下不分散混凝土修补的工程实例。As the Gongzui hydropower station has been operated more than 30 years, regular inspection and repairing is of great necessity .Results of the third round periodic inspection showed that the left-side guide wall of the No .7 spillway has been carved out a deep pit about 13 m in length, 3 m in height and 3 m in depth, which is of great threat to the safe operation of the spillway and the neighboring No .6 bottom outlet .This paper presents the subaqueous repairing work with underwater non-dispersed concrete for the eroded part of the left-side guide wall in the No .7 spillway in Gongzui hy-dropower station .
