通过波浪水槽断面物理模型试验,研究了"(开)"型浮箱在规则波作用下,透射系数与相对水深、相对宽度、相对入水深度、波陡、锚链夹角和锚链拖地长度等影响因素的变化规律.结果表明:"(开)"型浮箱的透射系数受相对宽度的影响最大,透射系数随着相对宽度的增加而减小,当相对宽度大于0.35时,透射系数不超过0.5,当相对宽度达到0.5左右时,透射系数降低至0.23~0.38之间;与矩形浮箱相比,除反射波能外,"(开)"型浮箱对波能也有一定的耗散和阻挡作用,其消浪效果要优于矩形浮箱.%A new type of floating breakwater of pontoon structure was proposed and studied by two?dimension?al wave flume physical model experiment under the regular wave action. The relation between the transmission coef?ficient and relative depth, relative width, relative submergence depth, wave steepness, angle between mooring axes and vertical at the joint,mooring line length and so on were studied. The results show that transmission coefficient is high sensitive and regular to relative width,it reduces with relative width increasing. When relative width is great?er than 0.35,transmission coefficient will less than or equal to 0.5. When relative width is reach about 0.5, transmis?sion coefficient will reduce to 0.23~0.38. Comparing with rectangle pontoon, (开)?shaped pontoon can dissipate and resist wave energy besides reflecting, so its wave dissipation effect is superior to rectangle pontoon.
