The Application of Carbon Fiber in the Reinforcement of Highway Bridge Cracks
In order to explore the effect of carbon fiber in crack disease treatment of highway Bridges,this paper takes a bridge project as an example to investigate the disease state of the bridge,and puts forward the reinforcement scheme.According to the construction practice,the deflection of the main beam and the strain at the monitoring point have decreased significantly after the carbon fiber reinforcement treatment.Compared with the actual measurement deflection and the theoretical calculation deflection,the actual measurement result is lower than the the-oretical calculation result,and the calibration coefficient is always maintained in the range of 0.60~0.90.The results show that the flexural bearing capacity of the bridge after carbon fiber reinforcement is significantly improved,and the operation safety of the bridge is guaranteed.
