A -12m deep quay wall at Shinko-east area is one of the 17 high earthquake resistant quay walls constructed in the port of Kobe for the restoration of the damage by the 1995 Hyogoken-Nanbu earthquake. An embedded steel-plate cell configuration is applied to this quay wall as a high earthquake resistant quay wall for the first time. This structure has following properties:(1) shorter construction time, (2) no seabed improvement, (3) higher earthquake resistance, etc. This paper presents some topics in design, construction and seismic characteristics of the steel-plate cell structure.
