摘　　要：沙质海岸由于其活跃的泥沙运动,在修建突入海中的建筑物后,建筑物附近岸线会有较大变化,为方便对沙质海岸建筑物下游侵蚀问题和防护措施的进一步研究,基于前人的研究成果对上述内容进行综述。结合毛里塔尼亚友谊港等多个典型工程案例,从岸线变化和剖面变化两方面对沙质海岸建筑物下游的海岸变化规律进行分析。探讨丁坝、出水离岸堤及离岸潜堤3种防护措施附近的水沙运动机理,对人工养滩及旁通输沙这2种软防护措施进行综述。最后就沙质海岸建筑物下游海岸侵蚀问题及相应的防护措施未来的研究方向做出展望。Due to the active sediment movement in sandy coasts,great changes may develop in the shoreline near the building after it is built into the sea.The downstream erosion problems and protective measures of buildings in sandy coast are reviewed and summarized based on the results of previous studies to facilitate further studies.On the basis of several typical cases such as that in the Friendship Harbor in Mauritania,the law of coastal changes in the downstream of sandy coastal buildings is analyzed from the aspects of coastline variation and sectional variation.The mechanism of water and sediment movement near protective measures such as groins,offshore breakwaters and offshore submerged breakwaters,is discussed,and soft protective measures such as artificial beach cultivation and by-pass sediment transport are summarized.Finally,the prospects for future research on coastal erosion of downstream sandy coastal structures and corresponding protective measures are given.
