采用不规则波对斜坡式防波堤进行了试验。不仅对入射波、反射波的波谱进行了分离,而且模拟合成了入射波、反射波的波形。明确了不同特征波的反射率也不同;反射波与入射波比较,波高分布有变化且波数减少,周期变长。将入射波、反射波的波形叠加后得到的合成波形与实测合成波形吻合较好,验证了波形分离方法的正确性。
Slope breakwater was tested with irregular wave. Not only the incident wave, reflected wave spectrum were separated, and the simulation of the incident wave, reflected waveforms. It is clear that the reflectivities of the different characteristic waves are also different. Compared with the incident waves, the wave height distribution changes and the wave number decreases, and the period becomes longer. The synthesized waveforms obtained by superposing the waveforms of incident wave and reflected wave are in good agreement with the measured synthesized waveforms, which proves the correctness of the waveform separation method.
