摘　　要：泄洪底孔进水口检修闸门采用半球形闸门,主要用于在下游的泄洪底孔事故闸门或流道需要检修时在静水中关闭切断流道水流。半球形闸门在国内的应用极为罕见,笔者结合半球形闸门在斯瓦克大坝泄洪底孔进口检修闸门中的应用,介绍闸门门叶、门槽的结构形式、锁定形式和导向装置的设计,可供类似工程参考和借鉴。The bulkhead gate of the bottom outlet intake adopts a hemispherical gate which is mainly used to close and cut off the flow channel in the still water when the accident gate or flow channel of the downstream bottom outlet needs to be repaired.The application of hemispherical gate in China is extremely rare.Based on the application of hemispherical gate in the bulkhead gate of the bottom outlet intake in Thwake Dam the author introduces the design of structural form of gate leaf and gate slot dogging device form and guiding device which can be used as reference for similar projects.
