PROBLEM TO BE SOLVED: To provide a foundation structure of an off-shore wind turbine generator, which can sufficiently exert wave resistance and achieve a reduction in construction cost and an increase in working efficiency.SOLUTION: In a foundation structure of an off-shore wind turbine generator, a gravity-type caisson is installed on a seabed, and a wind turbine structure is arranged in an upper part of the caisson. The caisson is formed in a polygonal cylindrical shape from a polygonal bottom and an exterior wall part vertically erected from an outer peripheral part of each side of the bottom.SELECTED DRAWING: Figure 1 【課題】本発明は、耐波性を十分に発揮でき、工費の低減と作業効率の向上を実現できる洋上風力発電装置の基礎構造を提供する。【解決手段】海底地盤上に重力式のケーソンが設置され、当該ケーソンの上部に風車構造物が配置される洋上風力発電装置の基礎構造であって、ケーソンは、多角形の底部と、当該底部の各辺の外周部から垂直に起立する外壁部とにより多角形の筒形形状に形成されている。【選択図】図１
