| 摘 要： | 对冲刷与粗化的相互作用机制进行了分析,并在非均匀沙床面暴露度的随机分布特性、流速分布及起动规律研究的基础上,提出了河床冲刷粗化的随机模型。该模型能同时对河床冲刷深度及粗化稳定级配进行计算。由实验及野外实测资料的验证表明,计算结果与实测值基本相符。

| Abstract: | This paper analyses the coaction mechanism between scouring and armoring. Based on the research of stochastic distribution characterstics of exposing height for nonuniform sediment, the velocity profile.and the law of threshold motion, the stochastic model of scouring and armoring for riverbed is put forward. The model can calculate scour depth of riverbed and armoring steady graduation simultaneously. The testing and verifying result show that the calculating results are corresponded with observed values on the whole. |
