摘　　要：调压井内设置事故检修闸门有两个目的:一是对压力钢管及厂内蝶阀进行事故保护;二是当压力钢管下平段或厂内蝶阀需要例行检修时,可利用此闸门挡水。笔者从结构受力、运行方式、运行安全、施工、投资等方面论证了某水电站取消调压井内事故检修闸门的可行性,为同类水电站工程引水系统中调压井内是否设置事故检修闸门的设计提供了一定的参考。There are two purposes for setting the emergency bulkhead gate in the surge shaft: one is to protect the penstock and the butterfly valve in the plant;the other is to use the gate to retain water when the lower flat section of penstock or the butterfly valve in the plant needs routine maintenance. The feasibility of canceling the emergency bulkhead gate in a surge shaft is demonstrated from the aspects of structural stress, operation mode, operation safety, construction and investment. It provides a reference for the design of emergency bulkhead gate in the surge shaft of similar hydropower station.
