Abstract: In order to improve the design level and delivery quality of Dongping Waterway Grand Bridge, the BIM design was carried out with Dassault 3D experience platform and TEKLA software as the main tools.The main technical points in BIM design include:collaborative design, skeleton design, approach bridgedesign, steel box girder design, steel tendon design and steel reinforcement design.The BIM application value of this bridge has the following aspects:steel quantity statistics, steel structure drawing, standard verification, finite element analysis, two-dimensional drawing of steel reinforcement.As the first cable-stayed bridge designed by BIM in China, compared with the traditional design method, the application of BIM technology significantly improved its design efficiency.At the same time, relying on this project, this article studied the data storage standard of railway engineering information model. BIM design of Dongping Waterway Grand Bridge has good reference significance for similar projects.
