BREAKWATER STRUCTURE, ENERGY ATTENUATION APPARATUS FOR WAVE OVERTOPPING AND METHOD THEREOF

摘要

Disclosed are a breakwater structure, a wave overtopping energy attenuation device, and an attenuation device for wave overtopping energy, capable of minimizing damage due to wave overtopping energy by attenuating the wave overtopping energy. According to the present invention, the breakwater structure includes: a foundation ground installed on a seabed; a unit structure having a block upper plate and a block lower plate formed with the same size in a rectangular or square shape and at least a column supporting the block upper plate on the block lower plate, wherein at least a through hole is formed on each of the block upper plate and the block lower plate; a front breakwater wall formed by stacking the multiple unit structures on a side toward open ocean on the foundation ground; a rear breakwater wall formed by stacking the unit structures on the side toward inland sea on the foundation ground, wherein the rear breakwater wall is separated from the front breakwater wall in a predetermined distance or more; and a wave overtopping attenuation layer including multiple wave overtopping attenuation plates and multiple support columns supporting each of the wave overtopping attenuation plates in order for the each of the wave overtopping attenuation plate to have at least one among a predetermined angle and a predetermined interval on a reference surface.
