在这项研究中，研究了部分穿孔沉箱防波堤上的总水平力和垂直力以及不规则波浪的相位差。部分穿孔沉箱位于碎石填充地基上，并填充岩石。基于线性势理论，利用匹配特征函数法和有限元法提出了该问题的简单半解析解。还进行了实验测试来验证理论模型并检查作用在穿孔沉箱上的波浪力。研究了一些主要因素对总波浪力和相位差的影响。理论和实验研究表明，当总水平力达到峰值时，同时总垂直（向上）力相当小，甚至变得向下。这是由于总水平力和竖向力的时程之间存在明显的相位差，这是穿孔沉箱相对于传统结构的重要优势。
In this study, the total horizontal and vertical forces as well as the phase differences of irregular waves on a partially perforated caisson breakwater are investigated. The partially perforated caisson is located on a rubble fill foundation and filled with rock. Based on linear potential theory, a simple semi-analytical solution of the present problem is developed by means of the matched eigenfunction method and the finite element method. Experimental tests are also conducted to validate the theoretical model and examine the wave forces acting on the perforated caisson. The effects of some of the main factors on the total wave forces and the phase difference are examined. Theoretical and experimental studies show that when the total horizontal force reaches its peak, the simultaneous total vertical (upward) force is rather small or even becomes downwards. This is due to the existence of an obvious phase difference between the time histories of the total horizontal and vertical forces, which is an important advantage of perforated caissons over traditional structures.
