| Abstract: | For a highway T beam bridge increasing bearing reiniorcement as an example, tins paper introduced the design scheme of unbonded external prestressed reinforcement. Using the finite element software, it analyzed and calculated the effect of the reinforcement scheme to the T beam bridge reinforcement. Through the load test before and after reinforcement, it verified the reinforcement effect and accumulated some references for the design and construction of the bridge increasing bearing reinforcement. |
