HYDRAULIC MODEL EXPERIMENTS ON SLIDING STABILITY OF CAISSON BREAKWATER WITH GROUND ANCHOR FOR REINFORCEMENT

Abstract

  The rise of sea levels and the increase of wave forces which has been caused by global warming will cause the failure of breakwaters. The ground anchor for reinforcement is proposed as an anti-sliding method of caisson breakwaters. In this study, we conducted hydraulic model experiments with a scale of 1 to 30 model in order to investigate the sliding stability of caisson breakwaters with the ground anchor for reinforcement against wave forces. The results show that the caisson breakwater with the ground anchor for reinforcement increases the sliding resistance and reduces the sliding distance, and the larger the initial tension of the anchor is, the more effective as an anti-sliding method.
