초록
본 연구는 말뚝으로 보강된 블록식 방파제의 수평저항력을 실내모형시험을 통해 구하였다. 특히 말뚝의 근입깊이를 달리하여 말뚝의 수평저항력 및 휨모멘트의 변화 등을 분석하였다. 그 결과 0H 대비 1H, 2H, 3H, 4H에서의 수평저항력은 각각 1.83, 2.05, 2.47, 2.94배 커지는 효과가 나타났다. 사석층(H)까지 말뚝이 관입되었을 때의 수평저항력이 블록내에만 관입되어 있을 때 보다 1.83배 커지는 효과가 나타났다. 말뚝의 휨모멘트의 경우 후열에 배치된 말뚝이 전열보다 더 크게 나타났으며, 이는 수평하중을 받는 블록이 활동뿐만 아니라 전도가 동시에 발생함에따라 나타난 결과라 볼 수 있다.
Abstract
This study conducted to obtain the lateral resistance of a block-type breakwater reinforced with piles through an model test. In particular, the changes in the lateral resistance and bending moment of the pile were analyzed by varying the depth of the pile. As a result, the lateral resistance at 1H, 2H, 3H, and 4H compared to 0H increased by 1.83, 2.05, 2.47, and 2.94 times, respectively. The lateral resistance when the pile was penetrated to the riprap layer (H) was 1.83 times greater than when the pile was penetrated only in the block. In the case of the bending moment of the piles, the piles arranged in the rear row appeared to be larger than the front row, which can be seen as a result of the sliding as well as the overturning of the block subjected to the lateral load.
