| 摘 要： | 基于VOF方法建立了波浪与潜式双层水平板型防波堤相互作用的数值模型。数值研究了潜式双层水平板型防波堤的透射系数和波浪力。综合考虑了相对板宽B/L、相对波高H/D、波陡H/L、相对板间距S/D和相对潜深d/D等影响因素,给出了透射系数和波浪力荷载随这些影响因素的变化规律。为了方便工程实际应用,拟合出了透射系数和总竖向波浪力的计算公式。公式计算结果与试验结果进行了对比,二者吻合良好。

| Abstract: | A numerical model of waves interacting tablished based on the VOF method. The transmission with a submerged horizontal twin-plate breakwater was escoefficient and the wave force of the breakwater were studled. The effects of relative plate width B/L, relative wave height H/D, wave steepness H/L, spacing ratio S/D and relative submergence d/D on the transmission coefficient and the wave force were revealed. The simplified formula for calculating the transmission coefficient and the total vertical wave force on the breakwater has been derived from the numerical results. And the calculating results agree well with the experimental results. |
