Abstract

The wave height distributions in front of a vertically perforated wall structures for obliquely incident uni-directional irregular waves are mainly investigated by using 3D hydraulic experiments. The difference and similarity of wave propagation along the plain and perforated wall structures are investigated and particularly the effects of side walls in chamber and relative chamber width are analyzed. This study shows that the wave height distribution patterns for normalized wave heights in front of structure is significantly different between the plain and perforated wall structures, and the side wall in the chamber suppresses the growth of waves.

본 연구에서는 불규칙파를 대상으로 한 경사입사파 내습시 유공구조물 전면에서의 파고분포를 파악하기 위해 평면수조를 이용한 수리실험을 수행하였다. 본 연구는 파랑의 전파특성에 있어 무공구조물과 유공구조물의 차이점과 유사점에 대해 검토하였으며, 특히 유공구조물의 유수실 폭과 유수실내 격벽의 효과에 대해 검토하였다. 제체 전면의 상대파고는 유공구조물인 경우와 무공구조물인 경우에 매우 큰 차이가 있음을 보였으며, 유수실내 격벽은 연파의 발달을 억제시키는 것으로 나타났다.
