城市立交桥碳纤维加固试验

Test on the Carbon Fiber Reinforcement of the Urban Overpass

结合某城市立交桥4号桥梁体的具体病害情况,通过对不同加固方案的比较,提出采用粘贴碳纤维材料法对该桥进行加固。加固后的测试结果表明,采用碳纤维材料对既有桥梁进行加固不但可以有效地提高其承载力,增强其耐久性,且具有快速、经济、适应性广等优点。

Connecting with the concrete disease situation of the beam of No.4 bridge of a certain City＇s overpass, and through the comparison of the different reinforcing schemes, this paper puts forward the carbon fiber bending method for reinforcing the bridge. The detecting results after the reinforcement show that the carbon fiber material for reinforcing the existing bridge-beams can not only increase effectively the bearing capacity of the bridge-beams but also strengthen the durability of the bridge-beam, and the carbon fiber material possesses the merits of the rapid speed, the economic cost and the wide applicability.
