摘要
介绍了天兴洲公铁两用长江大桥铁路箱梁移动模架整体提升施工方法,主要包括地基承载力、钢管立柱、吊装钢箱梁的设计计算,结构稳定性计算,以及提升站安装时应该控制要点.实践表明,移动模架整体提升加快施工速度,移动模架的结构质量也易于保证;移动模架整体吊装有其自身特点和优势,在施工中安全可控,操作简单.
Introduced construction technology of box-beam MSS assemble and lifting in Tianxingzhou Changjiang Bridge,including the calculation of bearing capacity of foundation soil,strength calculation of the steel columns and box-beam lifting,the calculation of structural stability,and the key points of lifting station installation.The integral lifting and installation can speed up process of construction and guarantee the quality of construction.Practice indicates,movable shuttering form lifting had its own features and advantages,which was confirmed safe and controllable,and simple to operate.
