Abstract: The current situation of arch bridge vibration research and the current situation of concrete arch bridge fatigue research under overloaded vehicles were described. The significance of fatigue analysis on the concrete arch bridge was discussed with the consideration of the enlargement of the bridge vibration. A new thought that the problem of the fatigue of highway arch bridge is solved by controlling bridge vibration is proposed,and the solutions for the diseases of the small-span and medium-span arch bridge in mountainous area are also discussed.

Key words: concrete arch bridge, vibration, fatigue, vehicle-bridge coupling
