摘要
研究一种新的施工方法,将钢箱梁现场拼装、滑移、提升及顶推技术结合,形成钢箱梁一体化施工方法,实现了钢箱梁流水化安装工艺。同时,对钢箱梁顶推施工进行受力分析,确保施工中的结构安全。研究表明,该施工工艺及顶推计算分析方法合理可靠,极大地提高施工效率、缩短工期和节约成本。
A new construction method is researched,which combines the on-site assembling,slipping,lifting and pushing technologies of steel box girder,forms an integrated construction method of steel box girder,and realizes the streamlined installation technology of steel box girder. At the same time,the stress analysis of steel box girder pushing construction is carried out to ensure the structural safety in construction. The construction technology and the analysis method of pushing calculation adopted in this paper are reasonable and reliable,which can greatly improve the construction efficiency,shorten the construction period and save costs.
