摘要
以低含沙水流泥沙组成与调整模式及钱宁等提出的高含沙水流两种极端模式为基础 ,讨论了高含沙两相紊流情况下泥沙组成与调整的机理 ,提出了泥沙平均粒径随含沙量的变化模式等新概念 。
The paper discusses the mechanism of size distributions for suspended sediment of sediment\|laden flow and gives raise to a size regulating model of suspended sediment particles for hyperconcentrated flow which occurs on the Yellow River.Based on the model a theoretical equation for averaged diameter of suspended sediment is derived and verified by the field data of the Yellow River.
