铁路客站BIM模型自动化生成系统设计与实现

Design and Implementation of Automatic Generation System for BIM Model of Railway Passenger Station

以BIM为基础的智能建造已经成为我国工程建设信息化的主要方向。研究自动化生成技术在BIM自动化生成系统中的应用,开发面向BIM建模的自动化生成系统。以某铁路客站为依托,采用数据预处理、结构识别、三维引擎、构件参数库等技术实现对二维图纸数据的采集及三维模型的生成。研究表明,自动化生成技术在铁路客站BIM信息化建设中,可有效提高建模效率和质量,降低建模成本,在铁路客站智能建造领域应用前景广阔。

The BIM-based intelligent building has become the main direction of engineering construction informatization in China.This paper studies the application of automatic generation technology in BIM automatic generation system,and develops an automatic generation system oriented to BIM modeling.Taking a railway passenger station as an example,the collection of 2D drawing data and the generation of 3D model are implemented by adopting such technologies as data pre-processing,structure identification,3D engine and parametric library of components.The research shows that the automatic generation technology can effectively improve the efficiency and quality of modeling,reduce modeling cost in BIM informatization construction of railway passenger stations,and has broad application prospects in intelligent building of railway passenger stations.
