EFFECT OF THE LENGTH OF PILES UNDER THE GROUND ON BEHAVIOR OF PILES OF REINFORCED GRAVITY TYPE BREAKWATER WITH STEEL PIPE PILES

Abstract

 Reinforced gravity type breakwater with steel pipe piles have proposed to increase ability of tsunami resistance of breakwater. In this study, effect of the length of piles under the ground on the behavior of reinforcing piles are considered by model loading experiments. As a result, effect of reinforcement of pile’s behavior and breakwater’s behavior are different when length of piles are changed. A range of this study, it is proved that breakwater with short piles is reinforced as effective as one of long piles when there is a proper length of piles.
