摘　　要：依托某大型矿石码头,对近岸矩形重力墩式码头结构开展波浪物理模型试验,并采用设计中常用的理论解析方法计算码头结构所受的波浪力,以研究矩形重力墩式码头结构与顺浪之间的相互作用。采用局部整体物理模型试验,对码头及所在港池的周边构筑物进行模拟,测量码头结构处的波浪要素和矩形沉箱墩台的波浪力。通过分析物理模型试验的测量数据,总结矩形沉箱墩周边波高及波浪力沿波浪传播方向的变化规律,分析影响波浪沿程变化的因素。将试验测量数据与理论计算结果进行对比,探寻与试验结论拟合较好的计算理论,提出结构设计中的关键点,为后续类似工程的设计提供参考。Based on a large ore terminal, the model test and the calculation of wave force on rectangular dolphin wharf by traditional analytic methods were presented in this paper to study the interaction between gravity rectangular dolphin wharf in nearshore zone and consequent waves. The wave height and wave force on rectangular caisson and box beam were measured in the integrated physical model test which simulated the wharf and surrounding structures in the harbor. Through the comparative analysis of test data and calculation results, the variation rules of wave height and wave force around the wharf dolphin were summarized in this paper. The better fitting calculation theory was explored and the key points for structural design were proposed to provide reference for similar projects.
