摘要
因赣江南大道下穿桥施工,南昌大桥西引桥需改道通车。车辆改道行驶后将改变南昌大桥翼缘板受力模式。为了确保南昌大桥结构安全,必须对南昌大桥翼板进行加固。对此,采用钢桁架进行顶撑加固施工。该文介绍了南昌大桥梁板加固施工技术,可供同行参考。
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.
