Experimental Comparison of the Wave Force on Crown Wall of Sloping Breakwater Armored with Tetrapods under Obliquely Incident Waves

摘要

Physical experiments have been performed in a wave basin to investigate change of the wave loading on the crown wall under obliquely incident wave conditions.The measurement was carried out with wave incidence angle of 0,15,30 and 45°.The pressure transducers were placed on the front and bottom face of the crown wall to obtain horizontal and uplift force as well.It was found that both the horizontal and vertical force decreases with the incidence angle.Based on the analysis of the experimental data,a formula was suggested to estimate the reduction rate of horizontal and vertical forces under obliquely incident waves.
