摘要
通过介绍大跨度预应力悬臂箱梁挂篮浇筑的施工实例,重点阐述了大跨度悬臂箱梁施工监控的基本步骤,包括有限元计算模型的建立、结构预拱度的设置、结构线形的控制以及实测应变作出修正的方法。
By introducing the cantilever construction of engineering examples, the basic steps of large - span cantilever construction monitoring are expounds, including finite element calculation model, the structure of arch, gets the linear control and actual structure made of Strain.
