SUBSTRUCTURE OF HYBRID OFFSHORE WIND TURBINE WITH MULTI-PILE FOR REDUCING WAVE FORCES, AND CONSTRUCTING METHOD FOR THE SAME

摘要

PURPOSE: A wave power reduction type multi-row offshore hybrid wind power plant support structure and a construction method thereof are provided to improve safety of the support structure by reducing wave power which acts on the support structure. CONSTITUTION: A wave power reduction type multi-row offshore hybrid wind power plant support structure (100) includes a concrete base (110), a concrete cone (120), a concrete-filled charge multi-row pile (130), a member connection unit (150), and a foundation pile (140). The concrete cone has a cone or a pillar shape, and forms a gravity concrete block by being combined with the concrete base. The concrete-filled multi-row pile is connected to the upper part of the concrete cone to resist a compressive force which is generated by a superstructure and a part of an overturning and bending moment.
