摘要

摘要: 考虑由前开孔板和后实体墙组成的Jarlan型开孔潜堤结构，利用理论和试验方法研究波浪在潜堤上的运动。利用匹配特征函数展开法得到问题的理论解。利用已有极限条件下的理论解、分区边界元解和试验数据对本文理论解进行验证。研究表明：与双实体板潜堤相比，Jarlan型开孔潜堤具有更优的消浪性能，且受力较小。防波堤前墙开孔率、相对淹没深度、消浪室相对宽度的最优设计值为0.1-0.2、0.1-0.2以及0.3-0.4。交换前开孔墙与后实体墙的位置对透射系数没有影响。但是，将开孔墙设置在迎浪侧可以达到更低的反射系数。

Abstract: The wave motion over a submerged Jarlan-type breakwater consisting of a perforated front wall and a solid rear wall was investigated analytically and experimentally. An analytical solution was developed using matched eigenfunction expansions. The analytical solution was confirmed by previously known solutions for single and double submerged solid vertical plates, a multidomain boundary element method solution, and experimental data. The calculated results by the analytical solution showed that compared with double submerged vertical plates, the submerged Jarlan-type perforated breakwater had better wave-absorbing performance and lower wave forces. For engineering designs, the optimum values of the front wall porosity, relative submerged depth of the breakwater, and relative chamber width between front and rear walls were 0.1-0.2, 0.1-0.2, and 0.3-0.4, respectively. Interchanging the perforated front wall and solid rear wall may have no effect on the transmission coefficient. However, the present breakwater with a seaside perforated wall had a lower reflection coefficient.
