摘　　要：多层浮管结构的浮式防波堤是利用多层垂直漂浮于水体中的浮管对波浪进行拦阻,阻止波浪传播并使波浪破碎,浮体在波浪作用下上下浮动、前后摆动,干扰波浪水质点运动,破坏波浪内部的水流结构,达到消减波能的目的,研究针对多层结构间隔、孔隙率、入水深度比、出水高度这4项指标进行的对比分析,提出满足消浪效果下各项指标适合的取值范围。In the design of floating breakwater,multi-layer floating pipe structure vertically floats in water to resist wave spreading and break wave.Wave action causes the above structure floating up and down,swinging back and forth,which interfere the movement of water particle and destroy the flow structure inside wave so as to reduce wave energy.Comparative analysis is carried out on the basis of four indicators of the multi-layer structure,that is,interval,void ratio,the structural depth below water level and the structural height above water level.The range of values for a variety of indexes is proposed finally,which satisfies wave-dissipation requirement.
