| 摘 要： | "T变箱加固梁桥"是一种加固T型梁桥的新方法,通过在T梁的肋底采用高强膨胀螺栓和环氧树脂砂浆黏贴钢板,将原截面由T型截面转变成箱型截面,从而达到提高原桥承载力的目的。通过贵阳铁路跨线桥的加固案例分析,说明该法很好地利用箱型梁抗弯、抗扭刚度以及整体性能,具有节省工期、施工简便且不中断交通施工等优点。

| Abstract: | Changing T beam into box beam is a new method to reinforce the bridge with T girder.To improve the bearing capacity of the bridge,the original section is changed from T-section into box section,using the high-strength bolts and to epoxy mortar expansion paste plate in the end of the ribs of the T-beam.This new method makes good use of anti-bending ability and torsional rigidity of box beam;therefore,it achieves the target of improving the overall performance significantly comparing with the traditional T-be... |
