摘要
高墩大跨连续刚构桥主梁箱梁悬臂浇注采用菱形挂篮进行施工,通过建立空间midas有限元模型对挂篮设计时应考虑的混凝土浇注、主构件的强度及稳定性分析、锚固系统、挂篮行走等工况进行计算,为类似施工设计积累经验。
Diamond hanging basket has been adopted in main box girder cantilever casting of high - pier and long - span continuous rigid frame bridge. Through establishment of Space Midas finite element model, calculations have been carried out on operating conditions components, anchor system and hanging basket of strength and stability analysis of concrete casting and main movement that shall be considered during hanging basket design and providing reference for similar engineering.
