| description | Abstract This article aims to solve the problem of the vehicle bumping at bridgehead which caused by uneven settlement in the transition section of the road and bridge. Firstly, a new adaptive device was established. In addition, the mechanism of the device was revealed. Secondly, analytical calculations were performed for the hitch plate equipped with the adaptive device, the deflection equation was derived, and the analytical solution was compared with the numerical solution. Finally, the adaptive device was applied to the actual project, the elongation of the device was analyzed with the settlement of the hitch plate. The results show that the adaptive device can realize the smooth transition of the road-bridge connection section by self-adjustment. Thus, the bridge head jump can be avoided in the case of soil foundation settlement, overall settlement and slap slope. The analytical and numerical solutions of the maximum deflection at the end of the slab are 2.571 cm and 2.263 cm. The corresponding longitudinal slope change rates are 2.8‰ and 2.5‰. One year after the completion of the actual project, the elongation of the two devices is 1.63 cm and 1.97 cm, and the settlement of the end of the slap is 3.74 cm. The adaptive device can provide a reference for solving the problem of jumping traffic at the bridge head. |
