The present invention relates to an offshore non-driven-in large-diameter monopile foundation structure and a construction method. An object of the invention is to provide an offshore non-driven-in large-diameter monopile foundation structure with simple structure, convenient construction and clear mechanic behavior, and a construction method. The technical solution adopted by the invention is as follows: an offshore non-driven-in large-diameter monopile foundation structure suitable for rock foundations is characterized in that a drilling hole is drilled in a rock foundation, a large-diameter monopile is implanted into the drilling hole, the bottom of the large-diameter monopile is sealed by underwater bottom-sealing concrete, and the gap between the outer wall of the large-diameter monopile and the hole wall of the drilling hole is filled with a grouting material goofed by a grouting system that is preset inside the large-diameter monopile. The invention is applied to offshore wind power and other industries.
