摘　　要：钢筋混凝土临时叠梁门在水电工程临时挡水度汛中的应用早有先例,但在龙开口水电站高水头的坝后式厂房进水口检修闸门工程中应用还属首次。笔者介绍了地处Ⅷ级地震烈度场地的龙开口水电站厂房进水口2012年汛期采用预制混凝土临时叠梁门挡水度汛的成功应用,详细阐述了高工作水头下混凝土叠梁门的设计与施工要点,"土工膜+沥青麻丝+橡胶止水"的三道止水联合防渗漏设计为国内首创。Reinforced concrete temporary stoplog gate has been used in hydropower projects for temporary water retaining,but it is adopted for the first time at the intake of powerhouse with high water head at dam toe in Longkaikou Hydropower Station.This paper introduces the successful utilization of precast concrete temporary stoplog gate at powerhouse intake of Longkaikou Hydropower Station located in the place with seismic intensity VIII in flood season in 2012.It elaborates key aspects in design and construction of concrete stoplog gate under high operating head.The design against seepage and leakage incorporating geomembrane,asphalt jute and rubber seal is adopted for the first time in China.
