The invention provides an intelligent bridge expansion joint device and application thereof. The device comprises a movable plate surface part, a plane truss part and a supporting part; the plane truss part is composed of fixed hinges A, truss rods, movable hinges and fixed hinges B; when the relative displacement of the two ends of an expansion joint occurs, the height change of a truss is causedby the deformation of the plane truss; through the height complementation of lifting and falling of a support plate in the supporting part, the flatness of the movable plate surface part is ensured.Stress gauges are embedded in movable plates A and movable plates B, the stress generated by all axles is tested when a vehicle passes, and the passing time of the axles is accurately recorded. Goniometers are fixed on the movable hinges, and the included angles of the truss rods are recorded in real time. The weight of all the axles and the total weight of the vehicle are solved according to thestress values corresponding
