Simulation Of Canopy Construction Process Of Railway Station Based On BIM Technology

BIM is short of “Building Information Modeling”,it’s cored as “information”, it is a three-dimensional parametric digital model used in the construction of the entire life cycle.It contains information construction project life cycle, different stages of realization, integration sharing information between different parties, the nature of the application of information technology in the field.The main contents of this paper:1.Starting from the basic theory of BIM, summed characterized introduce BIM technology and standards in the application of the construction phase, the basic principles and processes BIM technology implementation, and finally describes the establishment of a three-dimensional model and architectural expression construct dynamic software platform.2.The application of BIM technology in the domestic large-scale railway station project as the background, the BIM technology is still in the exploratory stage in the premise of railway station building construction field, this paper focuses on the methods and steps of the visual modeling of the station canopy( 1) Using the principle of Revit are introduced, and the basic operation of Navisworks two software, components division, management principle and model of storage naming rules.(2)The establishment of three-dimensional model and dynamic simulation of the construction method and process of Revit and Navisworks two software, and demonstrate the simulation results. Summary of modeling experience and problems,to provide reference for improving the efficiency of modeling.3.Through the study of BIM technology in railway station canopy construction process simulation, summarize the ways to improve the efficiency of modeling and the accuracy of the model, and how to guarantee the accurate model to make it more beautiful. Analysis of the simulation results, the improvement of process modeling is summarized. Finally, application of the results of BIM technology in Railway Engineering, BIM technology in the railway station in the field of some limitations and suggestions.The completed railway shed 3D model and dynamic simulation of construction,due to the author’s limited knowledge, thinking of the deep is not enough in-depth,detailed, and there is still a gap with the actual project application.
