摘　　要：本文运用SIMPLE算法,考虑自由表面情况,建立了剖面二维水流泥沙数学模型。文中系统地介绍了自由水面网格自动调整、SIMPLE算法在剖面二维水沙运动模拟方面的应用等关键技术,提出了相应的水沙近底边界条件,实现了水流运动的动态显示,并将模型初步应用于小浪底水库坝前剖面水沙运动的模拟。The vertical 2-D sediment numerical model is established in this research. Different from previous research, the importance of the SIMPLE algorithm and free surface in the study of vertical 2-D model is emphasized in this paper. The boundary conditions of water and sediment near the fiver bed and the dynamic visualization of flow motion issue are discussed in the present study. This model is also applied to the simulation of flow and sediment transport in front of the dam of Xiaolangdi reservoir.
