Abstract

In general, the caisson having the perforated wall is used to for the purpose of reducing the wave reflection and wave overtopping. In this study, the hydraulic characteristics (reflection coefficient) of the perforated wall caisson chamber filled with aggregates (rocks) were investigated with hydraulic model tests. When the perforated wall chambers were filled with aggregates, the reflection coefficients would increase. However, it was confirmed that the rock filling method into the perforated wall chamber could secure the stability of the structures and satisfy the hydraulic characteristics at a certain level.

일반적으로 유공벽을 갖는 케이슨(유공케이슨)은 직립식 구조물 벽면에 유공부를 설치하여 반사파의 저감, 월파량의 저감 등의 목적으로 사용된다. 본 연구에서는 유공케이슨 유수실을 골재(사석)로 채운 형태의 구조물에 대한 수리특성(반사계수)을 수리모형실험을 통해 검토하였다. 유수실을 사석으로 채운 경우가 유수실이 비어있는 일반적인 형상보다는 반사계수가 크게 나타났으나, 속채움재를 유수실에 설치하여 중량을 확보함으로서 구조물의 안정성을 확보하고, 일정 수준에서 수리특성을 만족할 수 있는 것으로 검토되었다.
