CFRP plate is a new type of material with a serial of advantages such as high tensile strength, small contraction, environmental corrosion resistance and etc. The reinforced technology of CFRP plate not only can effectively improve the bearing capacity of components, stiffness, crack resistance and ductility, but also the original size and weight increase very little. Based on strengthen Xinshu Bridge, the paper introduced in detail the construction process and construction method, which is of great significance for guiding construction.
