| 摘 要： | 结构表面布孔可以减弱波浪载荷,而海水的层化将导致表面波和内波的二重绕射作用机制。对此,本文分析并计算了在二层海洋条件下大直径透空双圆柱的水波绕射作用,并分别与均匀海中透空和非透空双柱的相应结果加以比较。计算结果表明,在层化海洋中结构物的透孔性对减弱波浪力有一定影响,密度比变化对内波波浪力影响显著。

| Abstract: | Porous structures may diminish wave loads on them and ocean stratification may lead to a more complicated mechanism of diffracted water waves.This paper analyzes the water wave diffraction by a pair of porous vertical circular cylinders in two-layer ocean and makes comparison of the results between uniform ocean and two-layer ocean and between impermeable cylinders and porous cylinders.It is found that the permeability of the cylinders may have a significant influence on the wave forces,and the internal wave forces may have obvious changes due to the change of density ratios of the two-layer water. |
