摘　　要：入海河口建闸后 ,闸下淤积是普遍而严重的问题 ,针对永定新河河口建闸方案 ,利用河口的潮汐观测资料和本河口泥沙的基本特性 ,对纳潮冲淤的可行性进行了分析 ,在北方河口水源匮乏的情况下 ,利用纳潮冲淤是解决闸下淤积较为经济。Sluice deposition is a common and critical problem after a sluice be constructed at river outlet into the sea.The feasibility of silt washing by tide has been analysized on the basis of its estuary tidal data and sediment characteristics aiming at Yongdingxin river estuary sluice constructing program.Silt washing by tide can economically and effectively solve deposition at downstream reach of sluice on condition of estuary poor water resources in the north.
