摘　　要：利用ADV等先进的量测仪器,通过船闸局部水工模型试验和三维数值模拟,对高水头船闸闸室明沟的消能效果和消能机理进行研究,分析流速分布、剩余比能、水面波动和紊动能耗散率等参数的结果表明:明沟消能工出流掺混强烈,97%的耗能位于明沟区,扩散均匀,水面波动较小,消能效果较优。明沟型式结构简洁,可在我国高水头船闸中推广应用。The paper researchts the open ditch＇s energy dissipation effect by means of part lock model experiment and 3-13 numerical simulation. The results of 3-D flow field, remaining energy, water surface fluctuation and turbulent dissipation rate distribution show that the flow blend violently, 97% of the total turbulent dissipation rate lies in the open ditch, the flow diffuses uniformly, water surface fluctuation is small, so energy dissipation effect of the open ditch dissipater is excellent, and the open ditch layout is simple. Thus it is recommended to further strengthen its research and application for the high-head lock.
