BIM technology-based railway continuous beam prestressed pipeline accurate positioning method

The invention discloses a BIM technology-based railway continuous beam prestressed pipeline accurate positioning method, which relates to a railway bridge prestressed pipeline positioning method. Themethod is invented mainly for solving the problem that at present, prestressed steel beam space positioning is based on a two-dimensional design drawing, and deviation is likely to occur in continuousbeam construction. Based on a drawing, a complete engineering model and a database are established according to construction procedures and system coding requirements, a BIM model adopts Tekla software for modeling, and an IFC general format is exported by utilizing the BIM model and transmitted to Navisworks. And through Navisworks display software, three-dimensional display of components is carried out on the bridge engineering, and meanwhile three-dimensional collision inspection is achieved. Programming is conducted through C# language to realize one-key output of the spatial coordinatesof the prestressed steel be
