Data set - MSc thesis - Experimental research into the stability of crown walls on a rubble mound breakwater

In this study, the loading characteristics of a crown wall on a rubble mound breakwater are investigated using a 2D physical model. The study examines both overall stability (through sliding) and the temporal and spatial distributions of pressure along the face and base of the crown wall. A range of wave conditions is tested, with particular emphasis on the influence of foundation level on the loading characteristics. Additionally, a second breakwater core is used to assess the impact of permeability on the wave loading characteristics. The findings highlight the significance of both parameters and analyze the discrepancies between predicted and measured maximum horizontal and vertical forces after wave impact. Furthermore, a novel two-step method is proposed to improve existing design methods, enabling more accurate estimation of wave loads.

本研究采用二维物理模型，对抛石防波堤胸墙（crown wall）所受的波浪荷载特性展开研究。本研究同时以滑移为评价指标评估胸墙的整体稳定性，并分析其迎水面与基底所受压力的时空分布规律。试验设置多组波浪工况，重点探究了基底高程对胸墙波浪荷载特性的影响。此外，本研究增设第二组防波堤芯体，以评估透水性对波浪荷载特性的影响。研究结果凸显了上述两类参数的重要性，并分析了波浪冲击后，理论预测值与实测最大水平、竖向作用力之间的偏差。进一步地，本研究提出一种全新的两步法，用于优化现有设计方法，以实现波浪荷载的更精准预估。
