Based on the engineering case of a bridge with a design load of automobile-super 20 and road trailer-120 for large transport vehicles,the stress state of the bridge before and after reinforcement is calculated and analyzed.A scheme is pro-posed to change the 16 m span simply supported beam system to a(5+6+5)m three span continuous beam bridge system,ef-fectively solving the problem of insufficient resistance of slab and cover beams,and providing reference for similar projects.
