芜湖长江大桥西岸大跨度连续钢桁梁的架设中 ,采用后锚索预加压力代替平衡压重 ,减免了 12 0 0 0 k N的配重 ,简化了施工 ,缩短了工期。吊索塔架取消初张拉、一次起顶成功等都为大跨悬拼架梁积累了经验 In the erection of the long-span continuous steel truss beam in the West Bank of Wuhu Changjiang River Bridge, the pre-stress of the post-anchor cable was used instead of the balance weight to reduce the weight of 1200 kN, which simplified the construction and shorten the construction period. Suspension of the tower crane pull the first pull, a successful start and so have accumulated experience for large-span cantilevered beam
