| 摘 要： | 通过引入随机理论及其相关处理方法,详细分析随机概念下的泥沙冲淤模式,建立了基于随机理论的泥沙数学模型。此模型避开了恢复饱和系数意义不明、取值不确定问题,以及含沙量与挟沙力的复杂性问题。通过水库淤积、水槽冲刷及一般河道的冲淤计算应用,结果证明本模式定性合理,可与确定性的传统水沙动力学方法作对比。

| Abstract: | Based on stochastic theory,the paper made a detailed analysis of sediment process in a river that took sedimentation and erosion into separate consideration to avoid the uncertain issue of and,thus provided a good way to solve the problem of sediment exchange near bed.And then the stochastic mathematics model of sediment transport has been developed,which is proved to be qualitatively reasonable through the computing application of reservoir sedimentation,sink scouring and common river erosion and dispositi... |
