A basic shock insulation structure for a pier comprises a pier column (10) and foundation which is formed by a bearing platform (20) and a pile foundation (21); the pier column (10) bottom is provided with a pier column bearing platform (11) which is solidified into a whole with the pier column (10); the pier column bearing platform (11) is placed into a limitation concave pit (20a) which is formed in the top of the bearing platform (20); the bottom surface of the pier column bearing platform (11) is in surface contact with the bottom surface of the limitation concave pit (20a); a connecting element (30) is arranged between the pier column (10) bottom and the bearing platform (20). The basic shock insulation structure for the pier has the advantages of enabling A (reverse Y) type high pier continuous rigid frame bridge structure to effectively dissipate earthquake input energy, guaranteeing integrity of the bridge structure, improving reliability of seismic performances and meanwhile reducing costs for ductility design requirements.
