Abstract:
The super-scaled Mexi River double-track bridge of Zhengzhou-Wanzhou railway in Fengjie is a top-supported rigid-frame reinforced concrete arch bridge, with complex structure, narrow construction site, and harsh construction conditions. In view of the numerous construction, technical and management problems in the construction of the super-scaled bridge, the BIM technology is employed and investigated, to achieve the integrated application of oblique photography, finite element analysis technology and BIM technology. Good results have been achieved in deepening design and construction of the main works, as well as in design, deepening design and construction of temporary works. The application of BIM ensures the successful implementation of the project, which has improved the quality of the engineering construction and integrated project management level, and achieved optimization of technical and economic indicators during the entire project life cycle. And a set of BIM application flow that can be used for reference in the construction of super-scaled bridge project has been formed.
