With the rapid development of economic construction, bridge reinforcement is a common research topic facing some developed countries in our country and in the world. In this paper, we mainly introduce the reinforcement method of bridge deck reinforced layer that has been used in production, the reinforcement of welded steel bar, the reinforcement method of bonded steel plate, the method of structural system transformation, the reinforcement method of external prestressing and the reinforcement of longitudinal and transverse beams. The emphasis is laid on the principles, advantages and disadvantages, and the scope of application of each law.
