FOUNDATION STRUCTURE OF OFFSHORE WIND POWER GENERATION FACILITY, AND CONSTRUCTION METHOD OF THE SAME
To provide a foundation structure of an offshore wind power generation facility which can be constructed on a water bottom ground including a surface layer comprising a soft layer and a hard support layer under the surface layer and whose joint portion to a pile includes long-term reliability, and to provide a construction method which can realize improvement of workability, shortened work period and reduction of construction cost when constructing such a foundation structure.SOLUTION: A foundation structure 10 of an offshore wind power generation facility is constructed on a water bottom ground 50 including a surface layer 51 comprising a soft layer and a hard support layer 52 under the surface layer, to support the offshore wind power generation facility, and comprises: a gravity type bottom slab 11 positioned on the surface layer; a plurality of piles 12 penetrating the surface layer and intruding into the support layer so as to support the bottom slab; and a joint portion for joining the plurality of top ends of the piles with the bottom slab. The joint portion includes a plurality of holes formed in the bottom slab. As a filler G is filled in a space to be filled that is formed by the top ends of the piles positioned inside holes of the bottom slab, the piles and the bottom slab are connected.SELECTED DRAWING: Figure 1
【課題】軟弱層からなる表層と表層の下の堅い支持層とを有する水底地盤に構築可能であり、杭との接合部が長期信頼性を有する洋上風力発電施設の基礎構造、および、かかる基礎構造を構築するときに施工性向上・工程短縮・施工コスト低減を実現可能な施工方法を提供する。【解決手段】この洋上風力発電施設の基礎構造１０は、洋上風力発電施設を支持するために軟弱層からなる表層５１と表層の下の堅い支持層５２とを有する水底地盤５０に構築され、表層上に位置する重力式の底版１１と、底版を支持するように表層を貫通して支持層に貫入した複数の杭１２と、複数の杭の天端と底版とを接合するための接合部と、を備え、接合部は底版に形成された複数の孔を有し、杭の天端が底版の孔内に位置することで形成される被充填空間内に充填物Ｇが充填されることで杭と底版とが結合している。【選択図】図１
