| 摘 要： | 基于非均匀非平衡状态下挟沙力级配的研究成果,利用系统的黄河干支流资料,进行了混合沙挟沙力与实测含沙量符合性的对比分析。表明在非均匀沙不平衡输沙条件下挟沙力级配不同于悬沙级配,用挟沙力级配计算挟沙力更确切反映黄河干支流泥沙多来多排的输沙特点,说明该项研究成果在理论上是必要的,在实际中是可行的。

| Abstract: | The study is based on a research of suspended load gradation in non-uniform and non-equilibrium transport(NNT).Analysis of the difference of the sediment carrying capacity of sediment mixture and the measured sediment content in light of currently available data in stem /branch stream of the Yellow River is carried out.The result indicates that a difference between the sediment carrying capacity gradation and the suspended load gradation in NNT existed.Thus,the former is better for illustration of the chara... |
