Repair, Evaluation, Maintenance, and Rehabilitation Research Program: Stability of Dolos Overlays for Rehabilitation of Tribar-Armored Rubble-Mound Breakwater and Jetty Trunks Subjected to Breaking Waves

摘要

An experimental model investigation was conducted to obtain design guidance for dolos overlays used to rehabilitate tribar-armored rubble-mound breakwater and jetty trunks subject to breaking waves. It was concluded that: a. The stability coefficient is independent of sea-side structure slope for slopes of 1V on 1.5H and 1V on 2H. B. Stability showed some dependency on both d/L and H/d with minimum stability occurring at the lower values of d/L and higher values of H/d, i.e. longer wave periods in shallower water. c. The minimum stability coefficient observed significantly exceeds that obtained for new construction. Keywords: Armor units, Breakwaters, Jetties, Rubble mound. (jes)
