The invention provides an intelligent pier. The intelligent pier comprises a pier seat and a pier body, wherein the pier seat is arranged at the bottom of the pier seat, and an A/D converter is arranged in the pier seat; the pier body is arranged on the pier seat and comprises three reinforced concrete supporting columns, each reinforced concrete supporting column is composed of a vertical part and an arc-shaped part, the vertical parts are connected with the pier base, the arc-shaped parts support the bridge surface, every two vertical parts of the three reinforced concrete supporting columnsare connected with each other, and piezoelectric devices are arranged in the arc-shaped parts, and the piezoelectric devices are connected with the A/D converter through wires; cavities are formed inthe center of the reinforced concrete support columns, magnetorheological elastomers fill the cavities, electromagnetic coils is wound outside the magnetorheological elastomers, the A/D converter isconnected with the electromagnetic coils, and alternating current generated by the piezoelectric devices is converted into direct current by the A/D converter to supply power to the electromagnetic coils, so that a variable magnetic field is applied to the magnetorheological elastomers, and thus the rigidity of the pier is changed, the anti-collision capability of the pier is increased, and the service life of the pier is prolonged. The pier can absorb sound, reduces noise, and has high practicability.
