Implementing quadrangular hollow blocks on breakwaters is a common method for wave mitigation and ocean disaster prevention. In order to improve the wave-damping performance of conventional quadrangular hollow blocks, a new quadrangular hollow block is proposed. In this study, a series of physical modeling experiments were conducted in a two-dimensional wave flume to investigate the wave reflection and wave run-up height of a new quadrilateral hollow block under regular wave action. Test results showed that wave reflection and wave run-up height decreased with the breakwater slope. The wave run-up height increased with wave height, and the reflection coefficient decreased with wave height. Wave reflection and run-up height increased with the wave period. The reflection coefficient of the new quadrangular hollow blocks was lower than that of the conventional quadrangular hollow blocks and decreased with frame height. In addition, this study found that the reflection coefficient and relative run-up height increased with the average wave breaking parameter. The new quadrilateral hollow block has advantages in wave mitigation compared to the conventional quadrilateral hollow block.

新型生态空心立方体波反射与爬升物理实验研究

在防波堤上设置四边形空心块是减浪和海洋防灾的常用方法。为了提高传统四边形空心砌块的减波性能，提出了一种新型四边形空心砌块。本研究在二维波槽中进行了一系列物理模拟实验，研究了新型四边形空心块在规则波浪作用下的波反射和波上升高度。试验结果表明，波浪反射和波浪爬升高度随防波堤坡度的增加而减小。波爬升高度随波高增大而增大，反射系数随波高减小。波浪反射和上升高度随着波浪周期的增加而增加。新型四边形空心砌块的反射系数低于传统四边形空心砌块的反射系数，并且随着框架高度的增加而减小。此外，本研究发现反射系数和相对爬升高度随着平均破浪参数的增加而增加。与传统的四边形空心砌块相比，新型四边形空心砌块在减波方面具有优势。
