| 摘 要： | 结合物理模型试验,分析斜坡坡度、波陡、相对水深、护面类型和破波参数等因素对堆石防波堤不规则波浪反射系数的影响规律。将常用的Van der Meer公式,Seelig公式,Postma公式和Davison公式计算值和实测值进行比较,并结合试验数据,基于有效波高和平均周期定义的Iribarren数,得出堆石防波堤不规则波浪反射系数经验公式。结果表明,该公式能较好地计算不规则波作用下块石和扭王块体护面堆石防波堤波浪反射系数。

| Abstract: | Based on the physical model experiment, the influence of slope, wave steepness, relative water depth, the type of armour and wave breaking parameters on the wave reflection coefficient of rubble mound breakwaters is analyzed. And the measured reflection coefficient is compared with the commonly used Van der Meer formula, Seelig formula, Postma formula and Davidson formula. And an empirical formula of wave reflection adopted with the Iribarren number defined by effective wave height and average period is fitted with the experimental data. The results show that the formula can calculate the wave reflection coefficient well. |
