The invention discloses a building shake-proof correcting structure and a correcting method, which are used for solving the technical problem that follow-up jacking correcting for a house is affectedas damages on a lifting jack are caused by sudden relatively great pressure. The building shake-proof correcting structure comprises a top plate and a supporting box, wherein a buffer part and a lifting jack fixedly arranged under the buffer part are arranged in the supporting box; the buffer part comprises a buffer column and a cavity column which sleeves the buffer cavity; the bottom of the cavity column is sealed; a sealed accommodating cavity is formed between the bottom of the buffer column and the bottom of the cavity column; the accommodating cavity is filled with a buffer fluid medium,and the top of the buffer column abuts against the top plate through the fluid medium; a release channel is arranged on the side wall of the cavity column; one end of the release channel communicateswith the accommodating cavity through the inner wall of the cavity column, and the other end of the release channel communicates with the outer wall of the cavity column; the two ends of the releasechannel have height difference on the side wall of the cavity column, so that the fluid medium is released from inside to outside through the release channel while the buffer column is pressed. The building shake-proof correcting structure is simple in operation, and is used for performing jacking correction on a settling house.
