Lab research on wave dissipation characteristics of different armor blocks used in submerged breakwater

以斜坡式潜堤为研究对象,通过物理模型试验的方法,选取相对淹没水深、护面结构形式的糙渗系数、坡度等因素的变化对潜堤消浪特性的影响进行了研究。首先,分析了在规则波作用下相对淹没水深、护面结构形式的糙渗系数、坡度等因素对潜堤透射系数的变化规律,得到了各因素对潜堤透射系数影响程度,同时给出了波浪在潜堤附近传播时沿程波高变化情况。其次,采用与规则波相同的研究方法,分析了在不规则波作用下相对淹没水深、护面结构形式的糙渗系数、坡度等因素对潜堤透射系数的变化规律,得到了各因素对潜堤透射系数的影响程度,并给出了波浪在潜堤附近的沿程变化情况。

Regarding the sloping submerged dikes as an object of study, using physical model test method, we research the wave dissipation characteristics of submerged breakwater by selecting different relative inundated depths and rough permeability coefficients of surface protection structure type. Firstly, we analyze the changing rule of the transmission coefficient of the submerged breakwater due to various factors under regular wave, get the degree of influence of various factors on the submerged transmission coefficient, and obtain the variation law of the wave height along the ducts near the submerged breakwater. Secondly, using the same research methods of regular waves, we analyze the changing rule on the variation of transmission coefficient of the submerged breakwater under irregular waves, we get the degree of influence of various factors on the transmission coefficient of the submerged breakwater, and obtain the change of the wave along the way near the submerged breakwater.
