摘　　要：分析了建立黄河河口泥沙有限元模型的必要性,并结合黄河河口实际情况,建立了黄河河口二维潮流和泥沙数学模型。从数学模型模拟计算得到的潮位、流速和冲淤验证结果可以看出,由模型模拟的潮汐和潮流的等海洋动力特性以及泥沙冲淤和海底变形都与实测资料一致,表明建立的河口泥沙二维有限元数学模型可进行黄河河口的潮汐、潮流和泥沙运动及海底冲淤演变的模拟与预测。In this paper, the necessity of establishing finite element model of the Yellow River estuarine sediment is analyzed, and the two-dimensional tidal current and sediment model in the Yellow River estuary area is established on the basis of the practical Yellow River estuary condition. It is shown from the verification results for the computed tidal level, tidal current and sediment scour and deposition that the simulated tidal level and current values and the computed sediment scour and deposition variations are consistent with the observed data, which indicates that the two-dimensional finite element estuary sediment model can be used to simulate the Yellow River estuary sediment movement and predict the estuarine seabed scour and deposition variations.
