In recent years,under the trend of heavy railway load,the volume of passenger and freight transportation has increased greatly,which makes railway bridge diseases more likely to occur,and seriously affect the safety of train operation.Based on this,relying on the strengthening project of a heavy-haul railway simply supported T-beam bridge in Hengyang City,the external prestress strengthening method is proposed to improve the bearing capacity of the bridge,and the finite element software Midas civil is used to compare the bearing performance of the bridge before and after reinforcement through static and dynamic analysis,which proves that the reinforcement effect is good.
