The invention discloses an earthquake-absorbing energy-dissipating spherical bearing. An upper bearing plate, a middle bearing plate, a lower bearing plate and a bottom bearing plate are arranged in sequence from the top down; the bottom surface of the upper bearing plate and the top surface of the middle bearing plate are matching sliding planes; the bottom surface of the middle bearing plate andthe top surface of the lower bearing plate are matching rotary spherical surfaces; the bottom surface of the lower bearing plate and the top surface of the bottom bearing plate are matching sliding planes; baffle plates are vertically arranged on the four sides of the bottom bearing plate; limit plates are arranged on the baffle plates; cantilevers are arranged between the lower bearing plate andthe limit plates on the four sides; one ends of the cantilevers are fixedly arranged on the lower bearing plate, and the other ends of the cantilevers abut against the limit plates on the corresponding sides; elastic damping
