Transverse deformation resisting structure of bridge end track plate under action of earthquake

The invention discloses a transverse deformation resisting structure of a bridge end track plate under the action of an earthquake, and aims to effectively improve the anti-seismic performance of a ballastless track structure on a bridge. The track structure can keep the original geometric shape and position under the condition that the earthquake causes large deformation displacement of the bridge. The structure comprises track plates located at the end of a bridge and on a bridge structure adjacent to a bridge abutment, wherein the adjacent track plates are longitudinally connected into a whole through steel rails and longitudinal connecting devices, sliding mechanisms are fixedly arranged on the top surface of the bridge structure at intervals, the track plates are located on the sliding mechanisms, and the bridge structure can transversely swing relative to the track plates. 地震作用下桥梁端部轨道板抗横向变形结构，以有效提高桥上无砟轨道结构的抗震性能，在地震导致桥梁大变形位移的情况下，轨道结构能保持原有几何形位。包括位于桥梁端部与桥台相邻部位桥梁结构上的轨道板，相邻轨道板通过钢轨及纵向连接装置纵向相连成为整体，所述桥梁结构顶面上间隔固
