摘　　要：文章采用有限元软件Midas对某T形梁桥钢板-混凝土组合加固前后的应变、挠度的变化进行了分析,同时采用Ansys软件计算出加固前后的极限抗弯承载能力,结果表明:钢板-混凝土组合加固可以有效提高T形梁桥截面的抗弯承载能力。In this paper,the strain and displacement changes of T beam bridge before and after reinforced with steel plate and concrete are analyzed using finite element software Midas,meanwhile,the ultimate flexural bearing capacity is calculated before and after reinforcement using Ansys.Results show that reinforcement combining steel plate with concrete can effectively improve flexural bearing capacity of T beam bridge.

关 键 词：T形梁桥 钢板-混凝土组合加固 极限抗弯承载能力
