摘　　要：采用网格堵塞技术实现实际地形的模拟,采用有限体积法离散方程,采用SIMPLER算法求解耦合的速度场和压力场,并建立了沿宽度积分的垂向二维水流泥沙数学模型。将计算结果和试验资料进行对比,结果吻合良好。A 2D vertical finite volume model of tidal flow and sediment transport is established by laterally integrating Navier-Stokes equation.The orthogonal curvilinear grid is used,and actual topographic forms are generalized by jam technology of mesh,numerical equations is discreted using finite volume method,coupled equations of pressure force and velocity is solved by SIMPLER numerical modality.
