Lateral Resistance of Block Type Breakwater with Piles to Depth of Embedment

摘要

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.
