摘　　要：在研究国内外高水头闸门资料的基础上 ,根据东风水电站双曲薄拱坝的结构布置特点 ,中孔弧形工作闸门采取了伸缩式止水型式。通过对门体结构、门槽体型及止水装置的设计和试验研究 ,较好地解决了东风水电站中孔弧形工作闸门的振动、门槽空蚀及止水问题 。according to the features of structure layout of double curve arch dam of Dongfeng Hydropower station, radial gate at the middle orifice with expansion water stop was adopted. On the base of designing and research testing for structure of gate body, shape of gate slot, water stop, the problems such as vibration of radial gate, cavitation of gate slot and water stop are solved well, this has accumulated experience for type-selection and design of discharge gate operation in a high head.
