• Abstract: 现如今悬臂挂篮施工已大规模投入应用到大跨径的桥梁施工中，但挂篮施工中，模板的安装拆除一直都是一个难点。本文以某一预应力混凝土矮塔斜拉桥为例，尝试研发设计一种可实现空间吊装的新型挂篮系统，采用有限元软件建立挂篮整体模型并对其进行有限元分析，分析了5个工况下挂篮的总体受力以及变形状态。结果表明，本次研发的挂篮系统不仅可适应不同节段以实现大跨径斜拉桥悬臂浇筑施工，还可实现高效率模板安装拆卸，具有较高的适应性能、安全性能以及实用性能。
• Nowadays, cantilever hanging basket construction has beenwidely applied in the construction of large-span bridges, but the installationand removal of templates have always been a challenge in hanging basketconstruction. This article takes a prestressed concrete low tower cable-stayedbridge as an example to attempt to develop and design a new type of hangingbasket system that can achieve spatial lifting. Finite element software is used toestablish the overall model of the hanging basket and conduct finite elementanalysis. The overall stress and deformation status of the hanging basket under5 working conditions are analyzed. The results show that the developed hangingbasket system can not only adapt to different segments to achieve cantileverpouring construction of large-span cable-stayed bridges, but also achieveefficient template installation and disassembly, with high adaptability, safetyperformance, and practical performance.
