Abstract: The Kengwei gully where the upper reservoir of Zhouning pumped storage power station is located is a small thin debris flow gully. And Zhouning power station, Long'er power station camp, access tunnel of Zhouning power station, and access tunnel of Zhouning pumped storage power station, construction camp and other buildings are distributed downstream the Kengwei gully which are at risk of debris flow. Therefore, control measures are put forward to reduce potential risk of debris flow, for reference.

Key words: Zhouning pumped storage power station, Kengwei gully, debris flow, buildings, control

摘要： 周宁抽水蓄能电站上水库所在的坑尾沟为小型稀性泥石流沟，坑尾沟下游分布有周宁电站及龙二电站营地、周宁电站进厂交通洞，以及周宁抽水蓄能电站进厂交通洞、施工营地等建筑物，泥石流爆发安全威胁大，因此，笔者对坑尾沟泥石流治理设计进行了介绍，以降低泥石流爆发的威胁。
