预应力混杂CFRP/GFRP纤维布加固工程结构是一种新颖的加固方法，为验证其实际加固效果，以连云港地区某旧桥为研究对象。根据病害与实际情况，采取闭合裂缝、粘贴预应力混杂 CFRP/GFRP 纤维布和横向钢板等措施对该桥进行加固，通过加固前后静载试验评估加固效果、评定桥梁状态。结果表明：加固后桥梁整体刚度明显增强，各板协同受力，残余挠度与变形较小，预应力CFRP/GFRP纤维布加固效果显著。

Using hybrid prestressed CFRP/GFRP fiber cloth in engineering structure reinforcement is a new meth-od.In order to verify its actual reinforcement effect,an existing old bridge is used to be studied.According to the main diseases and actual situation,reinforcement measures are adopted such as sealing fracture,pasting the prestressed CFRP/GFRP fiber cloth and transverse steel plate.The results of state evaluation show that the reinforced bridge has a better integral rigidity and a smaller residual deflection.It shows a good reinforcement effect for the prestressed CFRP/GFRP fiber cloth reinforcement method.
