基于Revit的城市轨道交通盾构区间参数化建模系统研究

Research on Parametric Modeling Software of Urban Rail Transit Shield Tunneling Sections Based on Revit

Revit作为城市轨道交通车站建模的主流软件,由于缺少线性定位功能,无法实现盾构区间建模,因此导致车站和区间需要采用不同软件进行建模,在装配时需要进行格式转换从而导致数据缺失。研究基于线性定位系统的城市轨道交通盾构区间BIM建模方法,通过Revit API和SQLite外部数据库相结合,构建线性定位系统,可以为盾构区间全专业的构件提供精确的空间定位,在此基础上对多专业数据集成、构件库建立、算法及程序等方面进行研究,并开发了一整套盾构区间全构件精确建模系统,能够有效提高线性工程的BIM建模效率和质量,达到图模一致的效果。

As the mainstream modeling software for station modeling of urban rail transit,Revit cannot realize shield tunneling section modeling due to the deficiency of linear positioning function.Thus,different software programs are required for the modeling of stations and sections,and date loss is inevitable after the format conversion during the assembly.This paper studies the BIM modeling method for shield tunneling sections of urban rail transit based on linear positioning system,and builds the linear positioning system by combining Revit API and SQLite external database,which can provide accurate spatial positioning for components of all disciplines in the shield tunneling section.On this basis,this paper studies multi-discipline data integration,component library establishment,algorithms and programs,and develops a complete set of accurate modeling system for all components of shield tunneling sections,which can effectively improve the BIM modeling efficiency and quality of linear engineering and achieve the effect of consistent drawings and models.
