摘　　要：关于航道整治建筑物作用区水沙运动以及由此产生的建筑物变形和损毁的研究是航道治理研究的重要组成部分,有着重要的现实意义。文章对长江中游航道整治建筑物中丁坝、护滩(底)和护岸3种形式建筑物结构形式及作用区水沙特性研究进行了梳理和总结,发现目前相关理论推导和数值计算的成果众多,列举了代表性较强的研究成果,从研究角度和考虑因素两方面对比分析了已有成果,提出今后可在床面冲刷位置和规模综合作用下的破坏阈值问题、床面冲刷发展模式及修复方式、极端水文条件对建筑物运行损毁的影响等方面继续深入研究。The research on the flow and sediment movement in the action areas of waterway regulation structures and the resulting deformation and damage of such structures is an important part of waterway regulation research and has important practical significance.This paper summarizes the research on the structural forms of the three types of waterway regulation structures,namely spur dikes,beach protection(bottoms),and revetments,in the middle reach of the Yangtze River and the flow and sediment characteristics of their action areas.It reveals that relevant theoretical derivation and numerical calculation are fruitful.Then,it exemplifies the representative research results and compares them from the two aspects of the research perspective and factors considered.It suggests that further research can focus on the damage threshold under the combined effect of the location and scale of bed scouring,the development mode of bed scouring and repair methods,and the impact of extreme hydrological conditions on the operation and damage of waterway regulation structures,etc.
