Abstract：In this paper, an existing rigid frame arch bridge on the national highway G321 in Guangdong Province is used as the test object. In view of the typical diseases of these old bridges, we took 5 new arch ribs transversely, and then repoured and paved the bridge deck for the purpose of reinforcement. The practice shows that, the reinforcement scheme can improve the bridge bearing capacity and make sure that the construction will be safe and reliable. It can provide reference for the reinforcement and maintenance of the existing rigid frame arch bridge of the same type.
