WORKING PROCEDURE OF RUBBLE MOUND SEAWALL CONSIDERING THE RISK OF BULKHEAD DAMAGE DURING THE PERIOD OF CONSTRUCTION

During the period of the rubble mound seawall construction there is no armor stones or concrete armor units to protect the structure against wave forces. Therefore, if the recession occurs during the construction period, it should be considered that the completion would be delayed. In this paper, wave basin test has been conducted in multidirectional random waves to investigate deformations of rubble mound seawall with pier head during construction. And a substitute plan that is able to shorten the construction period about three month is proposed.
