碳纤维棒在桥梁加固中的应用

Application of carbon fiber bar in reinforcement of beam bridge

针对某公路桥梁简支空心板承载能力不足的情况,通过在梁底锚固碳纤维棒进行加固。分析了该加固方法的原理,提出了该方法的工艺流程。经现场试验研究结果表明,该加固方法对交通影响小、对桥下净空影响小、能提高简支梁桥的承载能力。

In view of the insufficient bearing capacity of simply supported hollow slab of a highway bridge,the reinforcement is carried out by anchoring carbon fiber bar at the bottom of the beam.The principle of the reinforcement method is analyzed,and the technological process of the method is put forward.The field test results show that the reinforcement method has little impact on traffic,less impact on the clearance under the bridge,and can improve the bearing capacity of the simply supported beam bridge.
