摘　　要："粘贴钢板法"是一种加固T梁桥的新方法,该法很好的利用了箱型梁抗弯、抗扭刚度大大优于T型梁的技术原理,通过在T梁的肋底采用高强膨胀螺栓和环氧树脂砂浆粘贴钢板,将原截面由T转变成箱型截面,从而达到加固并增强原桥截面的目的,该法较其他加固法具有节省工期,施工简便且不中断交通等优点,本文列出了笔者亲身参与设计和施工的一座T梁桥的加固案例,以供参考。＂Steel Plate Binding Technique＂ is a new measure to reinforce T girder.The technique is based on the principle that the bending rigidity and torsional rigidity of the box girder outstand the T girder＇s greatly.By binding steel plate under the rib of T girder by high strength bolt and epoxy resin grout,it can achieve the purpose that reinforce and strengthen the quondam bridge section.This reinforcement measure has more merits than others as it can save time,simply put into construction and not stop traffic,etc.This paper set a reinforcement example of the T girder which is designed and constructed by the author,just for referrence.
