摘      要：A floating breakwater(FB)has extensive potential applications in the fields of coastal,offshore,and ocean engineering owing to its advantages such as eco-friendliness,low cost,easy and rapid construction,and quick dismantling and *** FB composed of twin pontoons and multi-porous vertical plates is proposed to improve the wave attenuation *** wave attenuation performance is investigated for different FB structures and vertical plate types under different incident wave heights and periods using 2D wave physical model tests in a wave *** results demonstrate that the proposed FB has a better performance than that of the conventional single pontoon-type *** reduces the wave transmission due to its enhanced wave reflection and energy *** wave transmission coefficient of the proposed FB decreases with an increase in the number of layers and relative draft depth of the vertical ***,a further decrease in the wave transmission coefficient is not observed when the number of porous vertical plates is increased from 4 to 5 *** equation has been derived to predict the wave transmission of the proposed FB based on the experimental results.
