摘　　要：挡潮闸具有挡潮、蓄淡、泄洪、排涝等功能,但由于工程在不同程度上影响了闸下河道原有的水沙运动规律,可能造成闸下河道河床抬高、过水面积减小,进而导致河道淤积,影响了工程效益的正常发挥。通过对六垛南闸历年引河断面的观测资料、上游来水及泥沙来源情况进行分析,进一步研究闸下河道冲淤特征和减淤防淤措施,为挡潮闸能够充分发挥工程效益提供可借鉴的方法。Tide gate play an important role in blocking tides,irrigation,flood control and drainage,water resource utilization,and resisting storm surges.At the same time,it changed the original characteristics of water and sediment movement in the estuary.As a result,the river bed of the estuary is raised,the water area is reduced,and the channel is silted up,which greatly reduces the discharge capacity of the tide gate.Affects the normal performance of engineering benefits.By analyzing the observational data of cross sections over the years with the sources of upstream water and sediment,research on the characteristics of river sedimentation and anti sedimentation measures,to provide reference and methods for fully utilizing engineering benefits.
