涟水河大桥挂篮悬臂浇筑法施工技术的应用

悬臂施工法是从已建好的桥墩开始对称地、沿桥梁跨径方向逐段施工的方法。该文结合工作实践,针对连续箱梁桥采用挂篮现浇悬臂施工难度大的现状,介绍了涟水河大桥悬臂施工所用的挂蓝类型和特点,通过现场结构体系转换等施工工艺,分析了粱体施工过程中产生挠度的因素、现浇施工与测试、挂篮的拼装与预压、合拢段验算,可供类似桥梁施工参考。

Application of Form traveler Cantilever Construction Technology in Lianshui River Bridge

The cantilever construction method is the technology starting from a built pier symmetrically along the direction of the bridge span to construct segment by segment. In combination with the work practice, in view of the present situation that it is great difficult to construct the continuous box girder bridge by the form traveler cantilever construction method in site, the article introduces the type and characteristic of the form traveler used for the cantilever construction of Lianshui River Bridge, and a...
