EXPERIMENTAL STUDY ON STABILITY OF ARMOR STONES OF COMPOSITE MOUND

The relaxation of the construction criterion for leveling of armor stones in mound is expected to reduce the construction cost of a composite breakwater in Ise Bay. The “stability” of armor stones in the “non-leveling” and “heaping up” construction methods is studied in a hydraulic experiment. The r...

Summary:The relaxation of the construction criterion for leveling of armor stones in mound is expected to reduce the construction cost of a composite breakwater in Ise Bay. The “stability” of armor stones in the “non-leveling” and “heaping up” construction methods is studied in a hydraulic experiment. The result for these cases is compared with that for the general leveling. Additionally, the diagram giving the critical depth for an allowable damage rate of approximately 1% in the non-leveling method is proposed.
