PROBLEM TO BE SOLVED: To provide an earthquake-proof reinforcing structure of a pile foundation structure and a method of earthquake-proof reinforcement which can favorably improve earthquake resistance without causing any damage to the existing pile foundation, and which is excellent in execution performance.;SOLUTION: The earthquake-proof reinforcing structure A which is provided with an extension pile foundation 4 can improve the earthquake resistance of the pile foundation structure 1 by being integrally connected to a pile foundation 1d outside the pile foundation 1d of the pile foundation structure 1 from a plane view. The extension pile foundation 4 is composed of a reinforcing pile 3 and an extension slab 2 to which the reinforcing pile 3 is integrally connected. Then the extension pile foundation 4 is provided at a location apart from the pile foundation 1d, and is connected to the pile foundation 1d through the medium of a pin-joint member 5 which enables the extension pile foundation 4 and the pile foundation 1d to move relatively in the up-and-down direction.;COPYRIGHT: (C)2007,JPO&INPIT
