EFFECTS ON WAVE FORCE ON SUPERSTRUCTURE OF SLOPING BREAKWATER AND WAVE OVERTOPPING OF COVERING STATE OF WAVE-DISSPATING BLOCKS

Abstract

 In this study, hydraulic experiments were conducted to examine the influence of incomplete covering condition of wave-dissipating blocks to wave force acting on the superstructure and wave transmission due to wave overtopping at several cross sections. The incomplete coverge of sloping breakwater influences front wave force on the superstructure and therefore increase the possibility of the superstructure to slide. The influence of wave transmission coefficient due to wave overtopping was small due to the steel sheet pile wall installed at the harbor side of the breakwater. In addition, we examined a method of rearranging experiment datas using two cross section wave force measuring lines on the superstructure to evaluate the fluctuation of wave pressure data.
