考马拉堡港（Kaumalapau Harbor）是一个小型驳船港口，位于美国夏威夷州拉奈岛西南海岸。该港口由一个旧的、恶化的岩石碎石防波堤保护，最初建于1925年。该防波堤最近由美国陆军工程兵团（檀香山区）与夏威夷州联合彻底重建。海洋学设计考虑包括水深约21米（70英尺），并直接暴露于可能的10.7米（35英尺）飓风强度的风暴波。修复使用了31.8吨（35吨）Core-Loc™混凝土装甲单元的装甲层，这是迄今为止使用的最大的此类单元。Core-Loc单元是一种相对较新的装甲单元类型，其使用在设计和建造方面都面临挑战，以确保其性能最大化。特别注意的是制定一个核心-位置放置计划，以实现所需的单位包装密度，并利用严格的施工技术，以实现指定的装甲层放置。该项目为进一步制定Core-Loc使用的设计和施工指南做出了重大贡献。工程于2007年竣工，该项目获得ASCE夏威夷分部2008年杰出土木工程成就奖。
Kaumalapau Harbor is a small barge harbor located on the southwest coast of the island of Lanai in the State of Hawaii, U.S.A. The harbor was protected by an old, deteriorated, rock rubblemound breakwater, originally constructed in 1925. The breakwater was recently completely rebuilt by the U.S. Army Corps of Engineers, Honolulu District, in association with the State of Hawaii. Oceanographic design considerations included a water depth of about 21 m (70 ft) and direct exposure to possible 10.7 m (35 ft) hurricane strength storm waves. The repairs utilized an armor layer of 31.8 tonne (35 ton) Core-Loc™ concrete armor units, the largest units of this type used to-date. The use of Core-Loc units, a relatively new armor unit type, presented both design and construction challenges to insure that their performance capability was maximized. Particular attention was placed on developing a Core-Loc placement plan to achieve the required unit packing density, and utilizing rigorous construction techniques to achieve the specified armor layer placement. This project contributed significantly toward furthering design and construction guidelines for Core-Loc use. Construction was completed in 2007, and the project won the ASCE, Hawaii Section, 2008 Outstanding Civil Engineering Achievement Award.
