摘　　要：通过整体模型针对曹娥江大闸可能出现的正常和不利淤积面貌进行闸下冲刷研究,曹娥江大闸因其规模大、工程条件复杂,被誉为"中国潮汐河口第一大闸",模型分潮沟维护和洪水前拓宽潮沟两种工况进行试验,得到了不同条件下冲刷闸下淤积泥沙所需水量,结论与实测资料分析、水槽模型等得到的较为一致,相互印证,为工程的建设及运行提供了可靠的依据.Cao＇e sluice is known as ＂Chinese first sluice of tidal estuary＂ for its large-scaled and complicated conditions. The scour of Cao＇e sluice by physical model under normal and disadvantageous conditions are researched. Experiments, including tidal creek retain and tidal creek widenning before flood, provide the water volume in the scour. The conclusions are closed to those which me provided by field and flume experiments, and are practical for the construction and operation of the project.
