The main aim of the present work is to provide an experimental and numerical seabed pressure dataset beneath rubble mound breakwaters with submerged berms. The estimation of the seabed pressure variation under a breakwater with a berm, useful for designing such a kind of marine structure, needs to take into account the interaction of the structure with the waves and the soil. A parametric experimental study has been carried out by varying the berm configuration, the offshore wave conditions and the water depth at the toe of the breakwater, keeping constant the values of the porosity of the berm, the armor layer and the core. From the experimental findings, the role of submerged berms in attenuating the seabed pressure under porous structures has been identified. Then, the experimental data have been used to assess the reliability of a Computational Fluid Dynamics (CFD) based numerical model. Once validated, the numerical model has been used to extend the experimental dataset by performing a parametric numerical study. New empirical formulations, aiming to predict the seabed pressure under breakwaters with a berm, have been eventually proposed.

目前工作的主要目的是提供具有淹没护堤的碎石堆防波堤下方的实验和数值海床压力数据集。带护堤的防波堤下的海床压力变化的估计对于设计这种海洋结构很有用，需要考虑结构与波浪和土壤的相互作用。通过改变护堤配置、海上波浪条件和防波堤趾部的水深，保持护堤、防护层和核心的孔隙率值恒定，进行了参数化实验研究。根据实验结果，已经确定了水下护堤在减弱多孔结构下的海床压力方面的作用。然后，实验数据已用于评估基于计算流体动力学 (CFD) 的数值模型的可靠性。经验证后，数值模型已被用于通过执行参数数值研究来扩展实验数据集。最终提出了新的经验公式，旨在预测带有护堤的防波堤下的海床压力。
