Visual Expression Method Of High-speed Railway Deformation Monitoring Information Based On BIM

In order to ensure the advanced nature of the industry and improve the management level and production efficiency,China’s railway industry began to introduce Bulding Information Modeling(BIM)Technology which is like a raging fire in the construction industry,also obtained a series of preliminary research and application results.In the process of cross-border integration with BIM technology and high-speed railway industry,the greatest feature is BIM changes high-speed railway objects and the carried information expression method,leading to a new way of 3D visualization.Not only focusing on 3D modeling and effect display,BIM technology is more likely focusing on the data and information compared with traditional 3D visualization technology.Aiming at resent situation deformation monitoring professional content has not yet been incorporated into the railway BIM technology system,this thesis did a series of theoretical analysis and practical application verification on adaptability of BIM technology applied to the visual expression of high-speed railway deformation monitoring through investigation,literature research,applied research,etc.The main work is as follows:1.The adaptability of BIM technology applied to the visual expression of high-speed railway deformation monitoring was demonstrated.2.In order to build the foundation of 3D visualization model,this thesis studied 3D visualization modeling method based on Microstation software and created basic model library of Subgrade section CRTS I plate ballastless track and deformation monitoring points.3.This thesis summarized the classification and coding of railway data relating to the deformation monitoring model of high-speed railway for the first time from BIM perspective,appropriately expanded the lacking parts of model classification and coding in IFD standard about high-speed railway deformation monitoring and applied it to engineering example which met the attribute information elements requirements of the BIM model4.This thesis preliminarily established the construction process of high-speed railway deformation monitoring BIM model,finished Microstation MDL and MVBA development based on this process and formed deformation monitoring BIM tools--Visual Tools and quick positioning method for monitoring points.It completed BIM model of high-speed railway deformation monitoring,expanded software function on deformation monitoring point attributes and results management.Egineering example was used to verified it finally.Due to the lack of previous studies,this thesis would be a fundamental attempt and exploration,mainly discussing the following two questions:One is high-speed railway 3D visualization problem based on BIM technology;The other one is integrating deformation monitoring points with additional attribute information and monitoring results into BIM model.In the study of these two questions,the main purpose was to explain how to use BIM technology to process and expressed the high-speed railway deformation monitoring points which loaded attribute information and deformation information,finally introduced BIM technology as a form of information carrier into high-speed railway deformation monitoring field.It could provide a reference direction for improving railway BIM technical system,also contributed to informationization and diversified expression of monitoring results in informationization surveying and mapping era.
