Transverse connecting structure reinforcement and reconstruction method for prestressed concrete combined truss arch bridge
The invention discloses a transverse connecting structure reinforcement and reconstruction method for a prestressed concrete combined truss arch bridge. Based on the method, a transverse connecting structure arranged in the middle section of a main hole of the prestressed concrete combined truss arch bridge is reconstructed from a truss partition plate into a wall partition plate, and the wall partition plate is joined with the inner peripheral surface of a middle box, so that parallelogram-shaped cross section deformation at the middle section of the main hole can be effectively inhibited, and breakage and damage caused by the cross section deformation are avoided. Therefore, by the method, the overall stress performance of the prestressed concrete combined truss arch bridge can be effectively improved, and the operational performance of the prestressed concrete combined truss arch bridge can be recovered and improved.
