Zusammenfassung: | The utility model discloses a shear-resistant vibration-reduction type bridge deck pavement structure, belongs to the field of bridge construction, and solves the problems that a pavement layer structure of a bridge is easy to damage and the vibration reduction performance of the bridge is poor. The bridge deck structure comprises a bridge deck slab, a damping layer, a waterproof layer and a pavement surface layer which are sequentially arranged from bottom to top, wherein a steel bar truss is arranged at the joint of the bridge deck slab and the damping layer. The damping layer accelerates consumption of bridge deck vibration mechanical energy caused by vehicle loads, so that the vibration response amplitude and the vibration duration are reduced, driving is more stable and comfortable due to reduction of the vibration response amplitude, the influence of bridge vibration on surrounding environment vibration can be reduced, rapidly changing stress in bridge deck pavement can be relieved, and the service life |
