Abstract

Taking the case of Yongji high-speed Zaoyuan Yellow River Bridge in Gansu Province, the installation method of high pier and long-span curved light steel girder is discussed in depth. According to the construction characteristics of the project, three construction schemes of overall pushing, cantilever assembly and cable hoisting are proposed, and finite element model calculation, analysis and verification of the same depth are carried out. Finally, the comprehensive comparison and selection of the cost, duration and quality of the three schemes are carried out to determine that the cable crane is the best construction technology, which provides the technical basis for the investment decision of the builder and provides a more comprehensive reference for the construction technology of the same type of bridge.
