摘　　要：研究了平面二维全沙泥沙输移 (悬移质泥沙和推移质泥沙 )的数学模型及其应用 .文中对比了国内外常用模型的特点 ,结合笔者在平面二维全沙泥沙输移数学模型中的计算经验 ,分析各自模型的差异 ,特别是针对模型的数值计算方法及湍流模型的应用进行分析和说明 ,在此基础上建立平面二维全沙泥沙输移数学模型 SFST- 2 D.并将该模型分别应用于长江三峡工程坝区泥沙计算、波迪The depth averaged 2 D mathematical model for total sediment transport (suspended load and bed load) and its application have been presented in this paper. Both of Chinese numerical simulation and the West one have been compared. Especially the numerical methods and the turbulence model were accounted for when different cases of calculation were employed. Consequently the model SFST 2D has been used in the impact assessment study on the sediment transport of the neighborhood of the dam of Three Gorge Project and the erosion calculations downstream of Bodi Kexi project.
