摘要：The present study investigates experimentally the wave-dissipating performance of twin-plate breakwater under oblique random waves. Through extensive model tests, the effects of the relative plate width and relative wave height on the dissipating performance are investigated under various incident wave angles. The results show that the dissipating performance changes insignificantly within the measured range of 15 degrees similar to 60 degrees incident angles. The transmission coefficient kt under oblique waves fluctuates around the value under normal waves. In addition, the transmission was directly affected by the relative plate width, i.e., the transmission was 0.1 < kt < 0.15 for B/L < 0.5 and 0.5 < kt < 0.10 for B/L >= 0.5. In particular, under oblique waves the wave patterns after the twin-plate breakwater exhibited significant three-dimensional characteristics, which were different from those under normal incident waves. To validate the present experimental results, the measured transmission coefficients are compared to those of Neelamani and Gayathri (2006) under normal incident waves, and the comparison shows good agreement.
