Abstract

Number of coastal protection structures have been increased rapidly due to rising sea levels and deteriorated sea conditions. Coastal structures should be designed to meet coastal engineering requirements and ecosystem conditions, while they are not lost or removed. In this study, trapezoidal gabion block was developed for the purpose, and two-dimensional laboratory experiments were conducted to validate applicability of the block. The experiments were carried out with eight types of erosive and accretive wave conditions. As a result, it was confirmed that the gabion blocks have a feature of preventing erosion of beach. The newly designed gabion blocks could be an alternative as a countermeasure method for beach erosion.

최근 해수면상승이나 해상조건의 악화 등으로 인해 연안보존을 위한 해안구조물 수가 급격히 증가하고 있다. 해안구조물은 소실되거나 제거되어서는 안 된다는 조건에서 관련된 해안 생태계를 충족하면서 해안공학적 특성을 만족하도록 계획이 이루어져야 한다. 본 연구에서는 이를 위해 사다리꼴 형태의 개비온블록을 개발하였으며 이동상 2차원 단면실험을 통해 타당성을 검토하였다. 실험은 8가지의 침식형 및 퇴적형 파랑에 대해 수행하였으며, 실험결과 개비온 블록이 해빈단면의 침식을 억제하는 특성이 있음을 확인하였다. 새롭게 고안된 개비온 블록에 대한 실험결과 해빈침식 대책공법의 대안으로 가능성이 있을 것으로 판단되었다.
