摘　　要：通过将桥梁检测所得数据和理论计算的结果对比,阐明简支T梁采用增大截面加固方法的有效性和可行性。结合采用增大截面法加固的工程实例,通过理论计算分析。参照旧桥加固前后定期检测的结果,证明采用增大截面的方法对桥梁受力状况有明显改善。The data obtained from regular bridge inspections is compared with the results of theoretical calculations,and the effectiveness and feasibility of the reinforced T-beam reinforcement method is clarified.Combined with the engineering example of the reinforcement of the section-enhancing method,the calculation and analys is of the formula theory are emphasized.Based on the results of regular inspections before and after the reinforcement of the old bridge,it is proved that the method of increasing the section has a significant improvement in the stress conditions of the bridge,and has a certain extension significance for the reinforcement of existing old bridges.
