摘　　要：湍流拟序结构与泥沙及床面相互作用的机理,是目前国内外泥沙学术界研究的热点领域。本文针对单向流和振荡流底边界层的湍流拟序结构与泥沙相互作用研究状况进行了综述,重点论述了振荡流底边界层湍流研究的概况与今后需要开展的重点研究内容。The coherent structure of the turbulence and the interaction of the sediment and the bed are now much studied all over the world. The researches on the interaction between the turbulent coherent structure of the unidirectional flow and the oscillatory flow and the sediment are reviewed in this paper, in which the emphasis is on the studies on the turbulence of the oscillatory flow on the bottom layer. The major issues that should be studied in the future are pointed out and discussed in detail.
