摘　　要：双层开孔消浪板是一种新型消能结构,其结构通过上层开孔板和下层实心板两部分来解决结构的消能问题.文中通过模型试验的方法来验证结构的消能性能,同时,对双层开孔消浪板结构在规则波作用下的消能系数随3个主要影响因子(相对板宽B/L,相对开孔A/A0,波陡H/L)变化的结果进行分析.通过分析和比较消能系数与影响因子之间的相互关系,证明双层开孔消浪板结构具有较好的消能效果.Two-layer porous energy dissipation plate is a new type of energy dissipation structure, which mainly consists of an upper porous plate and a lower solid plate to solve the issue of energy dissipation for breakwater. In this paper, the structure＇s performance of dissipating waves was investigated in detail in the regular wave tests.Meanwhile, changes of energy dissipation coefficient with the three main impact factors （ relative plate width （ B/L）, relative opening （A/A0） , steep wave steepness （H/L）） were analyzed. The comparison and analysis of the energy dissipation coefficients with respect to different factors were presented. The results indicate that the two- layer porous energy dissipation plate has the good characteristic of dissipating waves.
