| 摘 要： | 斜向入射的不规则波在海岸结构物前发生反射形成入、反射波共存的波浪场,对这种物理场的入、反射波的分离是海岸工程研究的一个重要课题.改进了一种可用于斜向入射的不规则波分离的两点法,使得测波阵列的两波高仪可布置在结构物前任何方向上.将此方法应用于三维波浪水池的物理模型试验研究,试验了不同的两波高仪的组合、不同的基床高度、不同的入射方向和不同的波浪要素等各种条件对分离结果的影响,结果表明,各种情况在满足非奇异条件下可得到较好的分离结果.该方法计算简便,可以给出较准确的反射系数和入、反射波的频谱.

| Abstract: | How to separate oblique irregular incident and reflected waves in front of vertical wall mode in laboratory basin is studied, and a kind of two points method that can be used to separate the oblique incident wave in which the two gauges can be placed at any direction in front of vertical wall is proposed. To analyze the factors which can influence the separated results, the results with different conditions, such as the position of the two distinct gauges, the different sea bed height, the different incident wave height and peak frequency are tested. It shows that there are evidently different among those conditions, in partically, the influence of the position of two wave gauges is more dominant. |
