Abstract
Gunkan Island (official name: Hashima) is an island with an outer perimeter of approximately 1.2km and is protected by a vertical concrete revetment. Gunkan Island features a number of important modern industrial heritage facilities and RC (reinforced concrete) buildings, and for this reason it has been gaining attention as a cultural asset and touristic resource. This island was expanded six times since the Meiji Era, and the revetment is between 82 and 116 years old. Maintaining the revetment in a suitable state is important for preserving the island. This paper provides an overview of the revetment of Gunkan Island and describes the results of a durability survey and visual inspection of the revetment.軍艦島(正式名称:端島)は長崎半島の沖合に位置する外周約1.2kmの島であり,外周は直立式のコンクリート製護岸となっている。軍艦島には多くの重要な近代化産業遺産や貴重な建築物が現存しており,文化財や観光資源として注目されている。この島では明治期以降6回にわたって拡張され,築造された護岸は既に82~116年が経過している。今後の軍艦島全体の保全のためには,護岸を適切な状態に維持管理することが重要である。本稿では,軍艦島の護岸の概要を示すとともに,護岸全体の外観目視調査と合わせて,コンクリートの耐久性に関する調査を実施した結果について取りまとめた。
Gunkan Island(官方名称:Hashima) is an island with an outer perimeter of approximately 1.2km and is protected by a verticalconcrete revetment. Gunkan Island features a number of important modern工业heritagefacilities and RC (reinforced concrete) buildings,and for this reason it has been gaining attention as a cultural asset and touristic resource. thisisland was expanded six times since the Meiji Era,between 82 and 116 years old. Maintaining the revetment in a suitable state isimportant for preserving the island. This paper provides an overview of the revetment of GunkanIsland and describes the results of a durability survey and visual inspection of the revetment。军舰岛(正式名称:端岛)位于长崎半岛前海,外周长约1.2km,外周为直立式混凝土护岸。军舰岛上现存许多重要的近代化产业遗产和珍贵建筑物,作为文化遗产和观光资源备受瞩目。这座岛自明治时期以来经过6次扩建,所建造的护岸已经过了82 ~ 116年。为了今后军舰岛的整体保护,在适当的状态下维护管理护岸是很重要的。本文在展示军舰岛护岸概要的同时,结合护岸整体外观目视调查,总结了有关混凝土耐久性的调查结果。
