The research on the technology of the replacement of concrete filled steel tubular arch bridges
It analyzes the replacement technology of concretefilled 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.
