The invention provides an earthquake energy dissipation structure of a multi-pillar pier. The earthquake energy dissipation structure of the multi-pillar pier aims to improve the vibration reducing performance of a bridge so that the bridge keeps the structural integrity after an earthquake. The earthquake energy dissipation structure of the multi-pillar pier comprises a left side pier pillar (11) and a right side pier pillar (12) which are adjacent to each other, wherein an energy dissipation cross tie beam (20) is arranged between the left side pier pillar (11) and the right side pier pillar (12) or a plurality of energy dissipation cross tie beams (20) are longitudinally arranged at intervals between the left side pier pillar (11) and the right side pier pillar (12); the energy dissipation cross tie beam (20) comprises a steel structure cross beam (22), and soft steel energy dissipation members which are fixedly arranged at the two longitudinal ends of the steel structure cross beam (22); the soft steel energy dissipation members are connected with the left side pier pillar (11) and the right side pier pillar (12).
