摘要： A resilient wave reducing structure which reduces waves propagating on liquid surface from propagating over the reducing structure and a method of constructing the wave reducing structure. The wave reducing structure of the present invention may be used to form a calm water surface region for harbors, for areas where construction work is being done or for areas where marine sports are to be performed etc. The resilient wave reducing structure includes at least one energy absorbing device having a resilient body constructed on a bottom of the liquid bounding the region where waves have to be reduced and filled with surrounding ambient liquid. This reduces the amplitude of waves passing over it by consuming the wave energy while it deforms according to the pressure distribution change caused by the waves and by radiating its kinetic energy into the liquid and the ground surrounding it. Because the wave reducing structure is resilient and deeply submerged under water, it does not hinder ships from passing over it. Therefore, it becomes possible to create a calm region on a liquid surface without hindering a navigation of ships and without creating a danger of wrecking the ships.
