Abstract

The complex materials of fiber reinforced polymer are widely applied in civil engineering because of its features of light mass, thigh strength and anti-corrosion. The application of reinforcement methods of ordinary pasting fiber rein-forced polymer, near surface mount and prestressed fiber reinforced polymer are presented in this paper in order to main-train and reinforce bridge better and increase the service life of bridge’s members. The problems related to the duration of reinforced members pasted by fiber reinforce polymer for reinforce engineering structure are pointed out, including aging and duration performances of complex materials and its performance after solidification, influence on performance of girder body by slow contraction of adhesive, fatigue reliability and overall performance of reinforced structure. These problems have to be further studied and solved. The reinforcement technique of prestress will be applied in reinforcement of Railway Bridge.
