고파랑 대응 신형 소파블록 개발: R-A Block

Abstract

The Concreate Armor Unit (CAU) is an artificial structure to reduce the intensity of wave energy. Hundreds different shapes of concrete armor units have been developed since 1950. Recent development of armor units focused on cost, constructability besides stability. Research necessity of a new CAU for high waves is increased due to climate change. We developed the new CAU which protected against significant waves height of 10 m and was suitable for single layer such as Accropode and Core-Loc. The new CAU called Reverse-A (R-A) was analyzed and verified in laboratory tests. It had excellent stability in hydraulic tests with high waves but difficulties in fabrication and installation.ability besides stability.
