| 摘 要： | 在完成4片模型试验梁的制作、加固前后测试的基础上,对比分析了钢筋混凝土T型梁作加固增强处治截面转换成箱型梁前后的应变、挠度、剪力滞后效应、抗扭刚度和极限承载力指标。试验证明,T型梁截面转换成箱型梁后,新增设的钢筋混凝土底板能与原T梁协调变形、共同承担活载。该加固增强技术可有效提高T型梁桥的承载能力,广泛应用于实践。

| Abstract: | Based on the testing result of four model beams,the authors compare the strain,deflection,shear stagnant effect,stiffness of twist-resist and maximum bearing capacity between T beam and box beam.The results show that the reinforcement concrete backplane and T beam can togther assort with deformation and bear live load.The strengthening technology is effective to increase the bearing capacity and is practi sed widely.The result of testing approves that the strengthening technology of changing T beam into box beam is effective and useful. |
