【摘要】：对开孔倾斜平板在二维规则波作用下的消波效果进行了物理模型试验研究,在平板与静水面夹角为±15°的情形下,比较分析了平板开孔率为0%、10%、20%和30%时,其对波浪反射系数、透射系数的影响以及能量衰减系数随着相对宽度(平板宽度与波长之比)的变化关系。研究结果表明,两种不同夹角情形下,倾斜平板在与静水面成15°时的消波效果要优于-15°,相对宽度和开孔率均影响平板的消波效果。
[Abstract]:In this paper, the wave dissipation effect of inclined plate with open hole under the action of two-dimensional regular wave is studied by physical model test. When the angle between flat plate and static water surface is 卤15 掳, the ratio of open hole is 0% and 30%. Its influence on wave reflection coefficient, transmission coefficient and energy attenuation coefficient with relative width (the ratio of plate width to wavelength). The results show that the wave suppression effect of the inclined plate is better than -15 掳when it is 15 掳with the static water surface under two different angles, and the relative width and the opening rate both affect the wave dissipation effect of the plate.
