The invention discloses a damping fastener system. The damping fastener system comprises a lower elastic pad (6), a first base plate (5), a first elastic layer (4) and a second base plate (3). The damping fastener system comprises a second elastic layer (2), a supporting column (7), a connecting sleeve (9) and anchoring bolts (12). The second elastic layer (2) is located on the lower side of the second base plate (3). The supporting column (7) and the connecting sleeve (9) cooperate to connecting the first bate plate (5), the first elastic layer (4), the second base plate (3) and the second elastic layer (2) together. The damping fastener system is fastened on a track bed through the anchoring bolts (12). According to a high-level damping fastener based on a compression type, the base plates and the elastic layers are arranged alternately, so that the elastic layers are connected in series, low vertical rigidity is achieved, and therefore the high damping effect is achieved. Meanwhile,a steel rail can directly fall on the ground, the use safety is guaranteed, and the damping fastener system is accepted and popularized through the market.
