Hinge damage is a common problemin hollow slab bridge. In order to study the influence of paving layer on the lateral stiffness of hollow slab bridge after hinge joint damage，a finite element analysis model is established by using beam lattice method. The results show that after damage to the hinge joints of hollow slab bridges, the paving layer can act as a lateral load transfer，which improves the transverse force performance of bridges，And the lifting effect is even more pronounced when the damage occurs in multi-pass seams. At the same time，when the thickness of the paving layer is 10～20 cm，the greater the thickness of the paving layer，the greater the transverse stiffness of the bridge，however, the influence of the transverse stiffness on the structure is not obvious.
