Abstract

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.

테트라포드로 피복된 경사식방파제 상부구조물에 파가 경사 입사할 때의 파력 변화를 관찰하기 위한 수리모형실험을 수행하였다. 입사파향은 0, 15, 30, 45° 4가지로 변화시켰으며 상부구조물 전면 및 하부면에 파압계를 부착하여 수평 및 연직파력을 계측하였다. 실험을 통해 입사각과 구조물 전면이 이루는 각도가 증가할수록 수평 및 연직 파력이 모두 감소함을 확인하였다. 실험자료 분석 결과로부터 입사파향에 대한 수평 및 연직 파력 감소율 산정식을 각각 제시하였다.
