斜拉桥主梁挂篮悬臂施工控制

Construction Control for Stayed Bridge Cantilever Hanging Basket

邯武快速路邯武大桥主梁采用挂篮悬臂现浇法施工,为确保结构受力合理,避免施工中主梁截面出现应力过大,使合龙后桥面线形顺畅、美观,本斜拉桥主梁施工中采用反馈监控方法。通过对施工监控量测得出的实测数据进行仿真计算,得出调整量,纠正偏差,指导后续施工,使最终斜拉桥的线形、内力满足设计要求。

This article focuses on stayed bridge cantilever hanging basket construction of Hanwu Bridge girder in Han Wu Expressway,to ensure proper weight and avoid the excessive stress of main bean during construction as well as the outline and appearance problem.The article focuses on the construction of bridge girder with feedback monitoring;simulation calculation is carried out on the data got from monitoring to figure out the adjustment to guide the following construction so as to make the outline inner stress meet the design requirement.
