摘　　要：三峡船闸输水系统阀门设计拟采用双面板式反向弧形门。通过比尺为１７的物理模型，对阀门启闭力进行了试验观测，并分析了启闭力的时均变化过程、启闭力脉动及其频域特性。从减小阀门动水启门力的角度，对反弧门几何体形进行了优化。The reversed tainter valve of double plate type will be used in the TGP's lock filling and emptying system. By means of a 1∶17 scale hydraulic model of the lock culvert valve of the TGP, the tests for the valve hoist load were performed, and the time average variation course, the fluctuating loads and their spectrum characters of the valve hoist were analysed. For reducing the valve hoist under flowing water condition, the optimization tests for the valve configuration were conducted.
