| Abstract: | The west approach bridge of Nanchang Bridge is required for the diverted traffic according to the construction requirements of Ganjiangnan Avenue Underpass Bridge. The diverted driving of vehicle will change the stress mode of wing slab of Nanchang Bridge. In order to ensure the structural security of Nanchang Bridge, it must be to reinforce the wing slab of Nanchang Bridge. Therefore, the steel truss is used for the top bracing reinforcement construction. The article introduces the beam slab reinforcement construction technology of Nanchang Bridge able to be referred for the similar projects. |
