| 摘 要： | 本文从分析螺旋流流态入手，考虑泥沙的运动状态相似，讨论了螺旋流中均匀泥沙在有效重力和绕流阻力作用下成为悬移质的相似律，以及泥沙的起动相似和悬移相似的同一性问题；分析了螺旋流输沙过程中沿程阻力损失。它为螺旋流输沙的试验研究提供了可靠的理论依据。

| Abstract: | Starting form analysing the regime of spiral flow,this artical thinks over the kinematic analogy of sediment,and discusses the similarity of sediment as the suspended load affected by the effective gravity and drag of circumference,and studies the unanimity of initiation and suspension similarity.Analyses the relation of the head loss and sediment discharge.This artical provides reliable theory basis for the further research of sediment transport in spiral flow. |
