摘要
桥梁结构安全的影响因素有很多,其中最常见、最重要的影响因素就是梁体裂缝。裂缝降低了梁体整体结构性,使梁体承重能力快速下降,并且导致梁体内钢筋被腐蚀,严重破坏了梁体的耐久性。阐述了梁体裂缝产生的原因以及裂缝对桥梁结构的影响,对不同加固方法的优劣进行分析对比,可为防治梁体裂缝产生提供一定的参考。
There many factors affect the bridge structure, one of the most common and important influencing factor is the girder crack. Cracksreduces overall structural of beam body and make the bearing capacity of beam body fall fast, and led to beam rebar corrosion inside body. It damaged the durability of beam body severely. In this paper, we study the cracks of beam body reason and the impact of the bridge structure, and analyzed the advantages and disadvantages of different reinforcement methods, which can provide certain reference for the prevention and control of beam body cracks.
