EXPERIMENTAL STUDY ON SLIDING DISTANCE CHARACTERISTICS OF SLOPING TOP CAISSON BREAKWATER WITH WAVE DISSIPATING BLOCKS

Abstract

 The sliding distance of sloping top caisson breakwater with wave dissipating blocks was measured by hydraulic experiment. The sliding distance of the breakwater with a sliding safety factor by an irregular wave varied with the deformation in mound around the caisson toe as well as the wave period. This study presents the diagram to estimate the sliding distance of the caisson accumulated during a storm event, the rate of the subsided wave dissipating blocks, and the rate of increase in composite wave force for sliding the caisson, which are applicable to the operation and management of the breakwater.
