摘　　要：介绍了南昌市儒乐湖项目的工程概况。根据儒乐湖闸的水文及布置特点,拟定水闸过流能力的计算方法,并分析该计算结果。结果表明,闸上管廊对水流过流形态及过流能力影响显著,低水位呈平底闸过流特性,高水位呈隧洞有压流过流特性。该方法可为同类复杂边界条件水闸过流能力计算提供参考。An introduction was made on the general information of Rule Lake project in Nanchang City.The calculat⁃ing method of gate discharge capacity was determined according to the hydrological and layout characteristics of Rule Lake gate.The calculation results were analyzed and demonstrate the pipe gallery above the gate has signifi⁃cant impact on the flow pattern and discharge capacity.At low water level,it shows the flow characteristics of flat bottom gate.At high water level,it shows the flow characteristics of pressure flow in tunnel.This method may be ad⁃opted for discharge capacity calculation of gate with similar boundary conditions.
