The invention discloses a double-phase damping lifting floating slab damping mechanism for rail transit, and belongs to the field of damping mechanisms for rail transit, the double-phase damping lifting floating slab damping mechanism comprises a floating slab body and a damping cylinder mounted between the floating slab body and a foundation, and a buffer piece comprises an elastic damping metal ball and oil liquid for cooling. The damping metal balls and the solid-phase cavity are located in the solid-phase cavity and the liquid-phase cavity respectively, the solid-phase cavity and the liquid-phase cavity are located in the inner spaces of the damping cylinders on the upper side and the lower side of the valve plate respectively, and the damping metal balls are evenly distributed in the solid-phase cavity. According to the floating slab damping mechanism for the rail transit and capable of improving damping in the two phases, the damping metal balls are used for replacing spring structures in the prior art,
