ARMOURSTONE PARAMETERIC DESIGN AND PATTERN PLACEMENT

Rock armouring is an efficient and economical method of stabilising coastal structures. The hydraulic stability under wave actions graded rock armour in two or more layers has been the subject model studies, field analysis, design formulas that can estimate quantity damage on for given action. Engineering principles1 typically consider random placement, distributed graded, permeability constraints, controlled stone interlocking. These four conflicting parameters interact various ways. Design formula practical experience laboratory show amourstones are not entirely stable: some proportions rocks likely to be displaced over time.
