Y型墩上盖梁无支架施工技术研究

On Non-bracket Construction Technology of

针对共和新路高架桥Y型墩上盖梁无支架的施工特点 ,采用梁杆单元 ,对上盖梁施工过程的各工况进行了分步计算 ,并与现场测试结果进行比较 。

In view of the construction peculiarity of non-bracket const ruction trait of Y-shape pier upper plate beam in Gonghexin Road Viaduct project, the author uses the Beam-rod finite element to calculate the whole construction period by steps, compares the result with engineering practice, and finally proves, the calculation can offer reference for the construction and design of non-bracket upper plate beam.
