摘　　要：掌握港内的波高分布特征对港口布局建设意义重大,物理模型制模成本较高、过程较为复杂,相关的数值模拟大多仅考虑了由防波堤口门传播进来的波浪影响,而忽略了越浪作用。针对这些局限性,基于开源软件OpenFOAM,建立环抱形直立式防波堤的三维数值波浪水池,将越浪与不越浪情况下的数值计算结果和物理模型试验结果进行比较,验证数值模型的准确性。结果表明:该模型能够较好地模拟堤顶越浪过程及港内波高分布情况,可用于优化港口布局的进一步研究。It is of great significance for the harbor layout and construction to master the wave height distribution characteristics in the harbor,while the physical modeling process is expensive and complicated.Most numerical simulations only consider the influence of waves propagating through the breakwater entrance and ignore the overtopping effect.To address these limitations,this paper establishes a three-dimensional numerical wave pool for a encircled vertical breakwater based on the open source software OpenFOAM,and compares the numerical calculation results in the case of overtopping and non-overtopping with the experimental results to verify the accuracy of the numerical model.The results show that the model can simulate the overtopping process at the top of the breakwater and the wave height distribution in the harbor well,and can be used for further research on the optimization of harbor layout.
