摘要
本文首先根据床面泥沙状态转移的临界条件建立起不同状态转移概率的计算公式,进而对不同运动形式的床面泥沙之间的质量交换率进行了探讨,并导出相应的计算公式.作为质量交换率的初步应用实例,文章最后讨论了平衡输沙条件下的悬移质挟沙能力和推移质输沙率的计算方法。
Based on the critical conditions of transformation among various types of sediment Particles in motion near bed the formulae are first derived to calculate the changing proba- bilities among different existing states of particles. Then there is a discussion on exchange rates of mass of sediment among different states and the corresponding expressions are provided. As applicaons examples of the theory developed in this paper, two relations are formulated respectively for calculaing the transport capacity of suspended sediment and the equilibrium transport rate of bedload with calibration using a wide range of experimental and field data.
