The setting of the bridgehead slab can effectively alleviate the harm caused by the bridgehead bump, but the secondary bump may occur due to the fracture and void of the slab. Given the above problems, the influence of buried depth on the deformation of the bridge approach slab is studied through theoretical analysis and numerical simulation. The results show that compared with the conventional slab, the shear force of the slab is reduced and the service life is increased when the slab is deeply buried. The deep-buried slab can help to reduce the differential settlement of the road-bridge transition section and alleviate the phenomenon of vehicle bumping at the bridgehead. And the deeper the buried depth of the slab, the more gentle the settlement change of the transition section of the bridge.
