A FUNDAMENTAL STUDY ON CONSTRUCTION SCHEME FOR RUBBLE FOUNDATION OF DEEP WATER BREAKWATER FROM HOPPER BARGES

Yoshiharu Matsumi

Abstract


This study aims to establish the effective construction scheme of the rubble mounds which are constructed by discharging a large amount of rubble from hopper barges. The numerical simulation technique is developed to estimate the spatial geometry of individual rubble mound discharged from a hopper barge. The effective distance between the discharge sites of the barge which makes the uneven property of the mound surface a minimum is discussed in connection with the change in the spatial geometry of the discharged rubble, the water depth and the direction of barge allocation.
