[Abstract]:With the increasing of our country's economic strength, the level of productivity has been developed rapidly, the level of informatization has been improved constantly, and it has deeply influenced all kinds of social industries. In the field of bridge engineering, the design ideas and structural forms are becoming more and more advanced. The extensive management mode of the traditional industry leads to low construction efficiency and hinders the progress and innovation in the field of bridge engineering. The BIM model can cover all stages of the whole life cycle of the project construction and provide timely for the bridge from design to operation and maintenance. Complete and accurate information, and a platform for information exchange and sharing for project participants at different stages, with visualization, coordination and information integration at its core, throughout the life cycle of bridge engineering, The current civil engineering industry, despite its use of information technology as an auxiliary tool during the planning, design, construction and operational phases, can significantly improve the efficiency and quality of construction. However, the application of BIM technology in the bridge engineering industry in China is still in its infancy at present. There are few cases of using BIM technology integration in the whole bridge life cycle. The project participants have only heard of BIM technology in many cases. The main reasons are the lack of core modeling software of BIM in bridge engineering, the unformed standard of relevant BIM specification and the few cases of application of BIM in bridge construction. Using BIM technology to serve the bridge engineering in our country better. This paper takes the construction of tied arch bridge with 128m Nielsen system in Zhengwan railway as the engineering background. This paper mainly studies the application of BIM technology in the construction of steel pipe vertical column-Beere beam support system during the construction process of tie beam. Combined with the design drawings and the special construction scheme, the BIM model of the foundation support system is created. This paper introduces the development of BIM technology at home and abroad, starting from the definition of building information model (BIM1), applying BIM technology to the whole construction process of tie beam support, and carrying out the research work in the following aspects: (1) in this paper, we introduce the development of BIM technology at home and abroad from the definition of building information model. The core modeling software of BIM and the technical standard of IFC are introduced. It is clear that the selected modeling software and research direction. The application of BIM technology in bridge engineering design stage, construction stage and operation and maintenance management stage is different. It shows that BIM technology can effectively solve the problems that cannot be solved by traditional technology, and greatly improve the design quality and construction efficiency. It has brought considerable economic and social benefits to the construction unit.) based on Bentley Pro Structure, the modeling method of the steel pipe vertical column and belay beam support system in the construction process of the tied arch bridge with 128m Nielsen system based on the Bentley Pro Structure is studied. The parameterized member family library of 128m tied arch bridge is established, which can provide BIM model module for similar bridge BIM modeling. The 3D drawing of BIM technology in the construction process of tied arch bridge with 128m Nielsen system in Zhengwan-Wan railway is analyzed. The application of collision detection, material statistics and 4D schedule simulation, It is verified that the application of BIM technology in the construction of 128m Nielsen system tied arch bridge is feasible. The BIM model established in this paper provides a strong technical guarantee for the construction organization of the construction unit. Improve the level of field information management, greatly improve the efficiency of construction management.
