摘　　要：云南万家口子水电站导流隧洞具有灰岩地质复杂、水位变化大和使用时段较长等特点。在完成导流任务后,需采用混凝土堵头进行永久性封堵。文章介绍了万家口子水电站导流隧洞堵头的设计方案、结构布置和施工技术要求。经现场检查,未发现明显渗水现象,封堵效果良好,对类似工程设计具有一定的参考作用。The diversion tunnel of Wanjiakouzi Hydropower Station in Yunnan Province is characterized by complex limestone geology,large water level change and long service period.After the completion of diversion task,the concrete plug shall be used for permanent plugging.This paper introduces the design scheme,structural arrangement and construction technical requirements of the diversion tunnel plug of Wanjiakouzi Hydropower Station.Through on-site inspection,no obvious water seepage is found,and the plugging effect is good,which has a certain reference for similar engineering design.
