摘　　要：为了深入探究规则波浪对复式海堤越浪水体空间分布的影响,利用开源的计算流体力学软件OpenFOAM建立了二维数值模型进行模拟。模拟结果与实验数据的一致性,验证了数值模拟方法的准确性。数值模拟结果表明:在不同下坡比m_(1)的情况下,最大越浪都分布在相对离堤距离x/H_(s)=1的位置。而上坡比m_(2)和相对堤顶高程Rc/H_(s)的增加会导致整体越浪分布以及最大越浪位置的后移。此外,研究发现无量纲单宽越浪量Q^(*)越大,越浪分布就越分散;Q^(*)越小时,越浪分布就越集中。建议将易受波浪影响的关键基础设施布置在海堤后方x/H_(s)>1的区域,以避免越浪损害,研究结果可为复式海堤的实际工程设计提供参考。In order to study the spatial distribution characteristics of the overtopping water body of the compound seawall under the action of regular waves,the two-dimensional computational fluid dynamics numerical model of the open source software OpenFOAM is simulated,and the numerical simulation results are compared with the physical model test results,which are in good agreement,so as to verify the rationality of the numerical simulation.Numerical model outcomes indicate that the maximum overtopping is distributed at the relative distance from the seawall x/H_(s)=1 in the case of different downslope ratios m_(1).The increase of the upper slope ratio m_(2) and the relative structure freeboard Rc/H_(s) will lead to the overall overtopping distribution and the backward movement of the maximum overtopping position.In addition,We also found that the larger the dimensionless average overtopping Q^(*)is,the more dispersed the overtopping distribution is,and the smaller the Q^(*)is,the more concentrated the overtopping distribution is.It is recommended that wave-susceptible critical infrastructure be located behind seawalls in areas where x/H_(s)>1 to avoid overtopping wave damage.The research results of this paper can provide reference for the practical engineering design of compound seawall.
