摘　　要：通过现场试验和计算分析,对一座粘贴玻璃纤维布加固的混凝土桥梁的弯曲承载力、挠度、应变及其动力特性进行了系统的研究,结果表明加固后桥梁的承载力和使用性能均明显提高。在此基础上,指出我国《碳纤维片材加固混凝土结构技术规程》中梁的受弯加固计算方法还有值得商榷之处,尚需改进。Based on the field tests and corresponding calculation and analysis, the mechanical behavior of a concrete bridge strengthened with bonded glass fiber reinforced polymer sheets, like the flexural loading capacity, deflection, strain, and dynamic properties, was systematically studied. The results of the study show that the carrying capacity and serviceability of the strengthened bridge are significantly improved, and further to the study, it is also found that the calculation methods for strengthening the flexural loading capacity of concrete beams provided in the Technical Specification for Strengthening Concrete Structures with Carbon Fiber Reinforced Polymer Laminates of our country are not safe enough, and need to be improved.
