The main objectives of the proposed research are (i) to improve the understanding of the processes associated with the interaction of breaking/non-breaking waves and pile groups, and based on this improved understanding (ii) to develop wave load formulae for the prediction of wave loads on a vertical cylindrical pile within a pile group in different arrangements. To achieve these objectives, existing data sets from previous experiments in the Large Wave Flume (GWK) will be re-analysed, new wave flume experiments will be performed and a numerical model will be validated by the experimental data and applied for a more systematic parameter study, thus extending the range of conditions tested in the laboratory. For a more efficient analysis of all the data obtained from both laboratory experiments and numerical simulations, more generic computational tools will also be developed.

本研究的主要目标是（i）提高对破碎/非破碎波与群桩相互作用相关过程的理解，并基于这种改进的理解（ii）开发波浪荷载公式，用于预测不同布置的群桩内垂直圆柱形桩上的波浪荷载。为了实现这些目标，将重新分析大波浪水槽（GWK）先前实验的现有数据集，进行新的波浪水槽实验，并通过实验数据验证数值模型，并将其应用于更系统的参数研究，从而扩大实验室测试条件的范围。为了更有效地分析从实验室实验和数值模拟获得的所有数据，还将开发更通用的计算工具。
