摘要
对波浪作用下泥沙起动、推移质输沙率和悬沙浓度分布的基本理论和研究成果进行总结。目前研究成果众多,但是各家学者研究成果的适用条件,表达形式有所不同,从而造成在实际应用中的困难。关于各公式间产生差别的原因有待深入研究,从而找到应用范围更广的公式。对于非均匀沙起动和输运的研究今后应重点关注。对于悬沙浓度分布研究,应更多的针对破碎波。
This paper reviews researches on sediment threshold, bed load transport and suspended sediment concentration under waves. There are a lot of studies of sediment transport presently, but many differences on applicable conditions and expression forms, which cause difficulties in practical application. The reason for differences among each formula needs further investigation, and then a widely-used formula should be found. In future research, more attentions should be paid on non-uniform sediment incipient motion and transport. More attention should be paid to vertical concentration of suspended sediment under breaking waves.
