Abstract

The purpose of this study is to develop a new type of hybrid artificial reef that can solve the problems of construction, installation and operation of existing concrete type and steel type artificial reef, and to evaluate basic structural performance through static loading test. For this purpose, we evaluated the strengths and weaknesses of concrete type and steel type artificial reef in literature, and developed a new type of hybrid artificial reef which can effectively overcome the problems of each artificial reefs while maintaining the advantages of two artificial reefs as an alternative respectively. In order to evaluate the merits of the proposed hybrid artificial reef, it was confirmed that the possibility of securing the convenience of the proposed hybrid artificial reef in the field and the possibility of securing the desired advantages were confirmed. Also, the static loading test was performed to evaluate the basic structural performance of the artificial reef. Through the above study, it was confirmed that the developed hybrid artificial reef exhibited proper structural performance while securing easiness of making and assemble.mm) can be predicted to have a low value up to 60% of the strength of cylinders without reinforcement.

본 연구의 목적은 기존의 콘크리트형 및 강재형 인공어초가 가지고 있는 제작, 설치 및 운용상의 문제점을 해결할 수 있는 새로운 형태의 복합형 인공어초를 개발하고 이에 대한 기본적인 구조 성능을 정적가력 실험을 통하여 평가하는데 있다. 이를 위해 기존에 콘크리트형 및 강재형 인공어초의 장단점을 문헌적으로 평가하고 두 인공어초가 가지고 있는 장점은 최대한 유지하면서 각 인공어초의 문제점을 효율적으로 극복할 수 있는 새로운 형태의 복합형 인공어초를 개발하여 대안으로 제안하였다. 또한 제안된 복합형 인공어초의 제작, 설치시 장점을 현실적으로 평가하기 위해 단위 모듈에 대한 제작 및 설치를 수행하여 제안된 복합형 인공어초의 현장 설치 용이성 및 목표한 장점의 확보 가능성을 확인하였다. 또한 제작, 설치된 단위 모듈을 대상으로 인공어초의 기본적인 구조 성능 평가를 위하여 정적가력실험을 실시하였다. 이상의 연구를 통하여 개발된 복합형 인공어초가 제작, 조립의 용이성을 확보하면서 적절한 구조적 성능이 발현됨을 확인하였다.
