DOUBLE-COLUMN BRIDGE STRUCTURE WITH ENERGY- DISSIPATING AND SELF-CENTERING FUNCTIONS AND CONSTRUCTION METHOD

The invention discloses a double-column bridge structure with a self-centering energy dissipation function. The structure comprises: a cover beam, wherein a platform is located above the cover beam, and a groove is formed in the top of the platform; a beam body, wherein the bottom of the beam body is connected with a first energy dissipation support, and the side wall of the beam body is connected with a limiting device; a prefabricated pier, which is connected to the lower portion of the cover beam through a second energy dissipation support and an energy dissipation steel strand; and a bearing platform, which is connected to the lower portion of the prefabricated pier through a self-centering device and an anti-buckling connecting piece. According to the invention, the overall stability of the structure is enhanced, the anti-seismic performance of a component is enhanced, the service life of the component is prolonged, the component is easy to replace, installation and operation are simple and easy, construction difficulty is reduced, and construction space is saved.
