在河流二维双方程紊流泥沙模型及求解方法基础上，用拟合坐标生成了正交曲线网格；运用“露滩冻结”技术解决河道中边滩和江心洲等随水位波动边界位置发生相应调整的动边界问题．模型考虑了床沙级配的分层记忆和床沙质与冲泄质的划分．模型验证后，应用于赣江樟树～南昌河段航道整治工程方案计算中，取得了良好的效果．
On the basis of two-dimensional two-way turbulent flow and sediment model and its solution method, an orthogonal curvilinear grid is generated by using fitting coordinates. The application of “beach freezing” Correspondingly adjusted dynamic boundary issues. The model takes into account the stratification of bed-sediment gradation and the division of bed-sand and run-off quality. After the model verification, it is applied in the scheme calculation of waterway regulation project from Zhangshu to Nanchang reach of Ganjiang River and achieved good results.
