The main structures that comprise a tidal power plant are turbine structure, sluice structure, tide embankment and gate. Since these structures are founded on seabed ground, an extensive geotechnical site investigation to evaluate the engineering properties of field soils must be conducted prior to design and construction. According to the results of geotechnical site investigation conducted at the planned site for construction of Incheon bay tidal power plant, soft ground generally lie 7 meters below the seabed surface level. This research suggests the reliable and economical design of foundations and ground improvements required for construction of main structures in Incheon bay tidal power plant, with considerations on field conditions.
