【中文摘要】 本文论述了水动力泥沙数值模拟的发展现状与趋势。结合水流泥沙数学方程的推导，对其中某些参数的物理意义进行了探讨。 在水流数值模拟中，本文采用三角单元有限差分法对水流基本方程显式求解，用嵌套网格和移动水边界技术对大范围开敞浅滩水域具有旋转潮波性质的水流进行数值模拟，该方法简单实用，可有效解决此类水流流向难以模拟问题。 在悬沙输移和床面变形数值模拟方面，本文建立了两种模式：（1）基于回淤率公式的推广模式，即根据刘家驹淤泥质海岸航道港池淤积计算方法，从悬沙运动方程出发的地形变化动床模式。（2）基于悬沙对流扩散方程的数值模式，即在大量现场资料和对计算水域含沙量场验证基础上，计算研究区域内的冲淤分布。 将本文所建立的两种模式分别应用于某工程实例，取得较满意的结果。通过对计算结果的分析，对这两种模式进行了评述。 在论文研究的基础上，作者还提出了水流泥沙数值模拟尚需进一步深入研究的问题和思路。

【英文摘要】 In the present paper, a brief introduction to the numerical model on the hydrodynamicand sediment transport has been made. The background of basic equations and someparameters in the numerical model are discussed.This paper presents a two-dimensional depth-integrated numerical model, which hasbeen developed by using explicit scheme of finite difference method on the triangleelements. This hydrodynamic model combined with the nested grid can successfullypredict the complicated tidal flows occurring in the coastal area. It is very simple andhigh efficient.In this paper, two models to predict the bed deformation are proposed.One is obtained based on the equation of suspended sediment transport under theunsteady flow. It extended the Liu's formula and can be used to predict the bedevolution caused by the different coastal construction. This model is app1ied to predictthe bottom bed evolution in Binzhou Harbor located in the south of Bohai Bay.Results show that the computed patterns are in ...更多a good agreement with those measuredin the nature.The other is sediment transport model in terms of hydrodynamic model plus aconvection-diffusion equation with source and sink term representing the erosion anddeposition. After being verified by the sediment concentration, this model cancalculate the bed change during some tides. The computed result is qualitatively fittedwith the observed data. The detai1ed data of tide and sediment are required if the long-term prediction is wanted.Some aspects such as application and key problems in the model are discussed withcomments with the obtained achievements and the way to their further improvements.  还原
