越浪量是衡量斜坡堤安全性及有效性的重要指标。为了对越浪量进行系统的研究,采用了一种新型的波浪耦合数值模型(0-1BEM+VOF模型),并在此基础上详细探讨了斜坡堤断面形式(胸墙高度、平台超高、平台宽度、外堤坡度)与波浪要素(波陡、相对水深)等因素对越浪量的影响。数据处理时应用二变量的分析方式,并与他人物模实验结果进行对比,得到以下结论:相对胸墙高度Hc/H对越浪量系数具有十分显著的影响,它们之间存在指数反比关系;其它变量对越浪量也有一定影响,随着Hc/H的变化,变量与越浪量之间具有指数关系。
The overtopping rate is the important indicator for the efficiency and safety of a sloping breakwater. We used a new type wave numerical coupling model(0-1BEM+VOF), on this basis, we discussed the effect factors of crown height, platform height, platform width, slope on wave overtopping, wave steepness and relative water depth, which influence on the overtopping rate. By using bivariate analysis method and comparing with the experiment results, we concluded that the crown height Hc/ H has a significant effect on the overtopping rate, they have exponential inverse relationships, and other physical effect factors even have an influence on the overtopping rate, they have exponential linear relationships following Hc/ H changes.
