Abstract

Among government projects for reduction of coastal disaster, coastal maintenance project stage 1(2000~2009) and stage 2(2010~2019) to reduce coastal erosion and sedimentation are currently under process. In performing the coastal maintenance projects, it is necessary to install artificial concrete armor units for coastal protection. Presently in Korea, products manufactured in Japan are applied to the site, or blocks self-developed by the construction firms are installed. However, there is a lack of technical reviews such as verification of hydraulic characteristics, securing the stability and design techniques. This study is intended to develop waterfront shore protection blocks with good accessibility of people and excellent coastal disaster reduction and protection capability. Through this study, hydraulic characteristics and stability coefficients of shore protection blocks could be drawn.

연안재해 저감을 위한 정부 사업 중 연안침식 및 퇴적을 저감시키기 위한 연안정비 사업 1단계(2000년~2009년)와 2단계(2010년~2019년)가 현재까지 진행중이다. 이와 같은 연안정비 사업을 수행함에 있어 연안 보호를 위한 인공 콘크리트 피복재의 설치가 필요하다. 현재 국내에서는 일본에서 개발된 제품을 현장에 적용하고 있거나, 호안보호공 설치를 시행하는 건설사에서 자체 개발한 블록을 설치하고 있는 추세이다. 그렇지만 이에 대한 수리특성 검증 및 안정성확보 여부, 설계기법과 같은 기술적인 검토는 부족한 상황이다. 본 연구에서는 이런 점들을 보완하여 사람들의 접근성이 좋으면서 연안재해 저감 및 보호 능력이 우수한 친수형 호안 블럭을 개발하고자 한다. 본 연구를 통하여 호안블록의 수리특성 및 안정계수를 도출할 수 있었다.
