Research On BIM Modeling And Engineering Application Of Complex Bridges

In recent years,BIM technology has become well-known in the construction industry and its related theories have been improved continuously.And the application of this technology in housing construction has matured gradually,showing its unique advantages in the design,construction and operation phase in projects.However,the application and study of BIM technology in complex bridge engineering are still relatively few,and BIM technology's advanced functions haven't been shown.Therefore,thesis uses the Hangyong motorway do-uble track Ningbo section phase I project S1 section binhai interchange overpass as the research object,based on the secondary development of Revit softw-are and C# programming language.Thesis studied out a method for automatic-ally positioning of components based on the data of line and longitudinal sect-ions and the position and shape of each component of the full bridge,thereby realizing data-driven automatic modeling of complex bridges.Focusing on the complicated bridge BIM modeling carried out a research including the followin-g aspects:(1)Thesis summarizes a small number of parametric models with the analysis of various forms of beam,bearing,pier cap,pier body,cap,etc in Hangyong motorway double track Ningbo section phase I project S1 section binhai interchange overpass.By the setting of family parameters,this paper realizes the fast modeling of various complex components.(2)Thesis analyzes the Revit core modeling software combined with a small number of parameterized models summarized to study the creation of complex bridge parameterized family libraries(3)Thesis studies the secondary development method of Revit,a method for automatically positioning of components based on the data of line and longitudinal sections and the position and shape of each component of the full br-idge was created,thereby realizing data-driven automatic modeling of complexbridges.(4)After the complex bridge BIM model has been created,this paper cond-ucts research on engineering application,in order to verify the automatic mod-eling method of complex bridges,make sure it is reasonable.
