The invention discloses a circular wooden column-hole-hidden graphite hardwood-graphite layer-along-column foundation stone seismic isolation system which is mainly used for seismic isolation and self-resetting of the bottom of a wooden structure circular wooden column. The shock insulation system is composed of a round wooden column, hole-hidden graphite hardwood, concave spherical surface belt limiting edge column foundation stone, a graphite layer and an annular tempered glass sealing plate. The hole-hidden graphite hardwood is composed of a convex spherical section, a thick cylindrical section, a graphite-hidden hole and a thin cylindrical connecting key which are integrally processed, and the thin cylindrical connecting key is inserted into the round hole in the bottom of the round wooden column to achieve positioning butt joint.
