Study On BIM Of Urban Rail Transit Line Design Achievements

In recent years,with the development of computer database,multimedia,network,artificial intelligence and other technologies,the design work of urban rail transit line selection has developed from the traditional two-dimensional design environment to the present three-dimensional design environment.But at present,the three-dimensional design software related to urban rail transit line design is not based on BIM design environment,and the design results of existing design software are not implemented quickly and completely to realize the related research of BIM.Therefore,based on the design results of urban rail transit lines and the construction of three-dimensional scenes such as topography,buildings,roads and rivers around urban rail transit lines by Revit software,this paper studies the method of rapidly constructing three-dimensional models of lines such as bridges,tunnels and subgrade according to the results of line design.to realize the BIM expression of urban rail transit line design results.The specific main research contents are as follows:(1)Analied the topography of urban rail transit lines,the characteristics and data structure of three-dimensional scenes and line structures around the line,The main points and key problems to realize the BIM of urban rail transit line design results are studied.(2)The three-dimensional scene data of buildings,roads and rivers along the urban rail transit line are expressed by using the VCT file in two-dimensional GIS,then studied the method of modeling and expressing based on the two-dimensional GIS data along buildings,roads and rivers and other three-dimensional scenes.(3)The characteristics and categories of urban rail transit line related structures,and the method of creating urban rail transit line structures in Revit are studied.(4)Learn the two-time development method of Revit.According to the characteristics of different structures in the line,this patper studied the rapid BIM modeling method of urban rail transit line design results based on Revit two development method.(5)Taking the actual project in the interval section of Jialing River Road Station ~ Xiangjiang Road Station in Qingdao Hongdao~ Jiaonan urban rail transit line as an example,this paper realizes the BIM expression of the design results of the urban rail transit line.It proved that the method of this thesis is feasibility.
