摘要
分析了吊杆的更换技术,通过建立有限元模型对吊杆的承载力及安全系数进行了验算,对吊杆更换的施工前期准备及在更换过程中采取的技术措施进行了研究,提出了相应的技术建议,为处理类似工程问题提供了经验。
It analyzes the replacement technology of concrete-filled steel tubular arch bridges, and researches on the technical measures adopted during the process and the preparation before the replacement of concrete-filled steel tubular arch bridges through the calculation of the bearing capacity and safety factors of concrete-filled steel tubular arch bridges by the establishment of finite element model. The relevant proposals are raised up to provide experiences for similar construction problems.
