摘　　要：在讨论了潮流和波浪的基本方程式及其相似条件之后 ,阐述了本文作者近年来在潮流和波浪作用下泥沙运动基本规律方面取得的研究成果 .在此基础上 ,提出了悬沙和底沙物理模型的相似理论 ,特别是全沙变态模型的相似理论 .按此相似理论 ,可在一个模型中进行潮流与波浪共同作用下的全沙试验 .The basic equations of tidal currents and waves and their similarity laws are discussed.The results obtained by the author in recent years in studying the basic laws of sediment transport under the action of tidal currents and waves are expounded.Based on these results, the similarity theory of physical modeling for suspended and bed load transport is developed. This similarity law gives special attention to the distortion model of total sediment transport.According to this similarity theory,the experimental study of total sediment transport under the joint action of tidal currents and waves in one model can be carried out.
