The invention relates to a hydraulic vibration reduction device for a high-speed railway platform-column-free canopy. The hydraulic vibration reduction device for the high-speed railway platform-column-free canopy comprises a canopy round steel pipe column, a column foot, a micro-expansion fine aggregate concrete layer, a concrete foundation and a shear key. The column foot, the micro-expansion fine aggregate concrete layer and the concrete foundation are connected with hydraulic vibration reduction device bodies. Each hydraulic vibration reduction device body is composed of an anchor rod anda steel pressure bearing barrel filled with hydraulic oil, and the lower end, located in the steel pressure bearing barrel, of the anchor rod is provided with a piston pressure bearing plate; the anchor rod is anchored into the steel pressure bearing barrel through the piston pressure bearing plate; the steel pressure bearing barrel is arranged at the bottom of a bottom plate of the column foot, and rebars are welded to the outer wall of the steel pressure bearing barrel and anchored to the concrete foundation; and the upper portion and the lower portion of the steel pressure bearing barrel are both provided with pressurization guide pipes. When no train passes, the hydraulic vibration reduction device can provide pulling resistance, and the structure stability is ensured; and the train passes at a high speed and enables the canopy to be vibrated, the anchor rods in the hydraulic vibration reduction device vibrate up and down, hydraulic oil in the steel pressure bearing barrel consumesenergy after being squeezed, and in this way, vibration, caused by the train, of the platform-column-free canopy can be reduced.
