摘要
国内现行规范中未提供有胸墙斜坡堤最大单波越浪量的计算方法。基于FLUENT软件,运用多孔介质区模拟斜坡堤上的扭王字块。借助惯性阻力系数C、等效波陡、相对块体尺寸、相对坡肩宽度、相对胸墙高度、相对水深、相对堤顶超高等影响因素,开展扭王字块体斜坡堤单波越浪量的数值试验。给出不同坡度下单位堤宽的最大单波越浪量的系数C计算关系式。验证结果表明,该公式具有较好的精确性,这使得扭王字块护面斜坡堤单波越浪量的数值模拟可以独立于物理模型试验进行,从而丰富了规范内容,为扭王字块体斜坡防波堤工程设计提供了参考。
The calculation method of the maximum single wave overtopping of the sloping breakwater with breast wall is not provided in the current domestic code.Based on FLUENT software,the porous media area was used to simulate the accropode armor block on the slope embankment.With the help of inertial resistance coefficient C,equivalent wave steepness,relative block size,relative shoulder width,relative breast wall height,relative water depth,relative crest super elevation and other influencing factors,the numerical test of single wave overtopping of the accropode armor block slope dike was carried out.The calculation formula of the coefficient C of the maximum single wave overtopping per unit width under different slopes was given.The verification results show that the formula has good accuracy,which makes the numerical simulation of the single wave overtopping of the sloping breakwater of the accropode armor block independent of the physical model test,thus enriching the content of the specification and providing a reference for the engineering design of the sloping breakwater of the accropode armor block.
