Research On Intelligent Aided Design Method Of Metro Station Under BIM Forward Design Mode

As a large-scale underground project in urban construction,metro station construction requires many comprehensive considerations are needed in the design process,The wide range problems of difficult interaction in different professional,pipeline collision and mutual interference have not been effectively solved.With the development of information technology,the popularity of Building Information Model(BIM)has promoted the transformation of engineering design patterns from traditional two-dimensional CAD design to three-dimensional BIM model design.However,most of the applications of BIM technology in the architectural design stage are in the state of " over-modulation".This method does not really implement the forward design using BIM technology what the design work of BIM thinking and working mode realized " the application effect of the mold that one time construction is used multiple times" truly.Based on the actual needs of BIM forward design,with the help of BIM,which has the advantages of BIM’s visualization,optimization and collaborative design,this article studied the intelligent assistant design method of metro station.The main research contents are as follows:(1)The theory of BIM forward design and intelligent assistant design is studied.Combined with the design pattern of current construction project,the demand of intelligent assisted design in forward design mode is proposed.Compared with the applicability of currently available intelligent assisted design platform,built a development environment.Lay the foundation for the implementation of intelligent assisted design features.(2)Based on the metro design specification and the relevant standards of national building information model,the design criteria of metro station design conforming to intelligent assistant design was established.The quality of the model was ensured and the reusability of the model was improved,with the standard model library was built for intelligent assistant design and centralized management.(3)Combined with the actual requirements of automatic modeling and intelligent computing in the design process of metro stations,and related engineering design specifications,based on BIM forward design idea,the intelligent assistant design method is studied.By using Revit’s modeling capabilities and the functional expansion capabilities of API tools,C#is used as the programming language,the intelligent auxiliary design function modules of four metro stations are realized,which are including the intelligent selection and automatic modeling of the main frame of the metro station,the intelligent assistant design of the stairs and escalators,and automatic opening of the floor,the intelligent auxiliary design and automatic modeling of the entrance and exit,and the comprehensive control room of the station as an example,the intelligent auxiliary design and modeling of the station building is realized.Make design simple and intelligent.(4)Taking the actual project of a metro station in Shanghai as an example,the intelligent assistant design function module developed in the BIM forward design mode is used for intelligent assisted design,the three-dimensional information model conforming to the specification was automatically generated.And the feasibility of the intelligent assistant design method was verified.
