EXPERIMENTAL STUDY ON STABILITY OF ARMOR STONES OF COMPOSITE MOUND (PART 2)

Abstract

The relaxation of the construction criterion for leveling of armor stones in mound is expected to reduce theconstruction cost of a breakwater covered with wave dissipating blocks in Open Sea. The stability of armor stonesin the “non-leveling” and “heaping up” construction methods is studied in a hydraulic experiment. The result forthese cases is compared with that for the general leveling. Additionally, the diagram giving the critical depth for anallowable damage rate of approximately 3% in the non-leveling method is proposed.
