DESIGN OF SINGLE LAYER ARMOR UNITS CONSIDERING WAVE DISSIPATION CHRACTERISTIC AND STRUCTURAL STRENGTH

Abstract

 Design method for single layer armor units is proposed considering wave dissipation characteristic and structural strength. A new wave dissipating block has been developed from the viewpoint of stability, hydraulic characteristics, construction condition and so on. In order to investigate impact strength of the block, drop test was carried out, and corresponding FEM analysis was conducted to elucidate fracture mechanism of the block. Design method to satisfy the requirement of void ratio and structural strength is discussed based on FEM analysis.
