摘　　要：基于线性势流理论和匹配特征函数展开法,建立了斜向波与内部带水平多孔板开孔沉箱防波堤相互作用的解析解。通过与分区边界元解对比,验证了解析解计算结果的正确性。给出数值算例,分析了波浪入射角度、消浪室相对宽度等因素对开孔防波堤反射系数和波浪力的影响规律。研究结果可为物理模型试验和工程应用提供指导。Based on linear potential theory and matched eigenfunction expansion method, this study develops an analytical solution for oblique wave interaction with a perforated caisson breakwater with an inner horizontal porous plate, which is confirmed by comparing with a multi-domain boundary element method solution. Numerical examples are given to examine the effects of the incident wave angle and the relative wave chamber width on the reflection coefficient and wave forces. The research results may serve as reference for physical model tests and practical engineering.
