Fast Generation Of Subway Enclosure Structures In Revit

With the development of information technology in the field of manufacturing and other fields,the information and industrialization of the construction industry receives additional significance gradually.BIM(Building Information Modeling)technology can realize the information management of construction projects,and provide a visual information management platform for the planning,design,construction,operation and maintenance of the project.BIM,which apply the information technology to construction filed,is the trend of development in construction industy.Although the development of BIM technology in China started late,lacking of mature modeling software and project management platform,BIM still has its application value: collecting of professional models and checking the conflict between professional during engineering design;the construction simulation can guide the construction during construction.Autodesk Revit series software is widely used BIM modeling software,which can be used in a variety of construction fields.It can realise the modeling of architecture,structure,MEP and other professional modeling and coordination between the various professions.Due to the three-dimensional design has not yet been realized,the design results will be presented in the form of construction drawings.Creating models based on construction drawings can find the wrongs of drawings,such as drawing errors,leakage of something,components joint together,lack of components.It is usual in actual project that link CAD drawings into Revit and then create models based on CAD drawing.Since most enclosure structures of subway distribute regularly,the "copy","matrix","move" etc.function of Revit can be activated during modeling.However,the number of components of enclosure structures is large,and creating models by Revit’s basic functions is inefficient,thus,it’s necessary to make plug-ins that aim at fast modeling of subway.In this paper,the method of generating underground diaphragm walls at one time is studied by analyzing the representation of underground diaphragm walls in construction drawings;the method of fast generation of piles is studied by analyzing distribution regularities of the piles;the parametric generating method of pile steels is studied by analyzing layout regularities of the pile steels.Further develop on Revit according to these methods,and bring about fast generating of enclosure structures of subway.
