摘要
文章结合钱江八桥梁拱组合桥梁施工,对其顶推施工中的临时构件拆除顺序与吊杆的张拉顺序等施工关键技术进行研究,分析了整体顶推到位后体系的转换和吊杆的合理张拉力值,最终通过内力比较,给出了合理的拆除顺序和吊杆张拉顺序及张拉值。
Combined with construction of Qianjiang bridge which is spatial girder and arch combination bridge, key technologies of the removal sequence of temporary structures and tensioning sequence of suspender during incremental launching construction are studied, the system transformation after incremental launching is in place and reasonable tension value of suspender are analyzed, finally reasonable removal sequence and suspender tensioning sequence are given through internal force comparion.
