摘　　要：系统总结了近70 a来国内外保滩促淤方式的发展概况,着重对离岸出水堤、离岸潜堤、人工养滩以及丁潜坝组合形式下保滩促淤的水沙机理研究进行了综述,并对离岸潜堤、人工养滩等新型保滩理念以及丁潜坝组合方式提出了展望:分析和总结冲刷与淤积的临界关系式,掌握离岸潜堤的保滩规律;寻找"喂养"与"遮蔽"效应的最优契合点,提高养滩效果和使用寿命;研究丁潜坝组合中纳潮口规模对促淤效果的影响;加强"栖息海滩"的研究与应用。We systematically summarized the development of the beach protection and deposition protection methods both at home and abroad in the past 70 years,emphatically summarized the research on the mechanism of water and sediment in the offshore breakwater,submerged breakwater,nourishment beach,and the combination mode of groyne and submerged breakwater,and put forward the prospect of the new beach protection concept of submerged breakwater and beach nourishment,as well as the combination mode of groyne and submerged breakwater:Analysis and summary the critical relational expression of siltation and scour,grasp the protection regulation of submerged breakwater;find the best fit point of"feeding"and"shelter"effect,improve the effect and service life of the beach raising;discuss the influence of the scale of tidal inlet on the effect of deposition promotion of the combination of groyne and submerged breakwater;strengthen the researching and application of"inhabiting beach".
