[0002] Rubber bearings are widely used in rail transit bridge projects. They are not only used in ordinary railway bridges and highway bridges, but also widely used in urban rail transit facilities such as subways and light rails. By supporting and stabilizing the bridge structure, vibration and noise are reduced, and the riding experience of passengers is improved. When selecting and arranging rubber bearings, it is necessary to fully consider factors such as the structural form and scale of the bridge, and the shape of the horizontal, longitudinal and transverse end surfaces of the main beam. At the same time, it is also necessary to determine the position of fixed and slidable bearings according to the reaction force, movement and rotation direction of the bearings. Reasonable selection and arrangement can ensure that rubber bearings perform optimally in rail transit bridges.
