摘　　要：董箐溢洪道工作闸门孔口尺寸较大，启闭较为频繁，是国内已投入运行的超大型露顶式弧形工作闸门之一。本文介绍了该闸门启闭设备布置、门叶结构特点、框架设计思路、支臂扭角计算、侧水封及支铰轴承方案的比选，可为后续类似的超大型露顶式弧门设计提供借鉴和参考。The extra -large and frequently used service gate for the spillway of Dongqing hydropower project is one of the extra - large top - exposed radial gates operated in China. The paper introduced hoisting equipments layout, gate flap＇ s structure features, framework design idea, torsional angle calculation, side seal and hinge bearing schemes comparison, which can be referred by the later design of the similar extra - large top - exposed radial gate.
