| Abstract: | The deflection of cantilever top in many prestressed concrete T shaped rigid framed bridge leads to traffic jam This paper describes a new reinforcement technology of prestressed concrete T shaped rigid framed bridge, i e a combination technology of external prestress and internal non cohesive prestress which is successfully applied to Xiedie reinforcement bridge engineering. This method and technology are very useful and of great reference value to the reinforcement of long span bridges |
