先简支后连续小箱梁的桥梁施工工艺

Bridge Construction Technology of First Simply Supported and Second Continuous Small Box

先简支后连续小箱梁体系近年来在桥梁施工上逐渐得到推广使用,安装后连续段的浇筑张拉施工以及拆除临时支座的体系转换作业,不仅提高了桥梁的受力性能和行车的舒适性,同时也降低了桥梁的造价。

System of first simply supported second continuous small box has gradually been promoting the use of in bridge construction in recent years,tension construction pouring of installing continuous section and operating system conversion of removing temporary support improves the mechanical properties of the bridge and driving comfort,and also reduces the cost of the bridge.
