本文通过实验和计算，研究了椭圆余弦波与浅水中二维水平平板相互作用的水平和垂向波浪力。实验是针对两种水深、五种波长和四种波高的组合进行的，对应于非线性波在浅水中的传播。该模型位于六个不同的海拔和淹没深度，使所有可能的情况下，沿海桥面完全高于静水水位，甲板上的表面和完全淹没的甲板被认为是在研究中。计算进行相同的情况下，在实验室的实验，包括一个非线性浅水波模型的基础上的第一级格林-Naghdi方程的完全淹没的情况下，欧拉方程加上一个淹没的情况下，一个高架的情况下，和一个情况下，在水面上的流体界面跟踪方法的体积。比较现有的理论解决方案，包括长波近似基于线性势理论的淹没的情况下，和经验关系的情况下，高架。这里提供的一组数据提供了一个深入了解位于浅水区的沿海桥梁，码头和码头的甲板上的风暴波载荷。
Horizontal and vertical wave forces due to the interaction of cnoidal waves with a two-dimensional, horizontal flat plate located in shallow-water are studied through laboratory experiments and calculations. The experiments are conducted for a combination of two water depths, five wavelengths and four wave heights, corresponding to the propagation of nonlinear waves in shallow-water depth. The model is located at six different elevations and submergence depths such that all possible cases of a coastal bridge deck fully above the still-water level, a deck on the surface and a fully submerged deck are considered in the study. Calculations are performed for the same cases as in the laboratory experiments and include the results of a nonlinear shallow-water wave model based on the Level I Green–Naghdi equations for the fully submerged cases, and Euler’s equations coupled with the Volume of Fluid interface tracking method for one submerged case, one elevated case, and one case at the water surface. Comparison of existing theoretical solutions are also provided, including the Long-Wave Approximation based on linear potential theory for the submerged cases, and empirical relations for the elevated cases. The set of data presented here provides an insight into storm wave loads on the decks of coastal bridges, jetties and piers located in shallow-water areas.
