基于BIM技术的铁路隧道正向设计研究

以Bentley平台和二次开发软件为技术支持,对基于BIM技术的铁路隧道正向设计进行研究:结合新版软件功能,从项目创建、流程管理、参数化设计、三维建模、工程量统计等方面出发,总结BIM正向设计在可视化、参数化设计、信息化管理、结合地形设计等方面具有的优势;另一方面,BIM技术还存在部分构件建模过程复杂、二次开发软件不足、出图功能欠缺、参数化数字化设计不完善、审核难度大等问题。通过本次研究,进一步优化了铁路隧道BIM正向设计流程,为在隧道专业中推广BIM正向设计积累了宝贵的经验。

Research on Forward Design of Railway Tunnel Based on BIM Technology

Taking Bentley platform and secondary development software as technical supports,this paper studies the use of BIM forward design in railway tunnel. Combined with the functions of the new software,from the aspects of project creation,process management,parametric design,3 d modeling and quantity statistics,the advantages of BIM forward design in visualization,parametric design,information management and terrain design are summarized. On the other hand, some problems and suggestions are put forward, such as complicated modeling process of some components,insufficient secondary development software,lack of drawing function,imperfect parametric digital design and difficulty in auditing. Through this study,the BIM forward design process of railway tunnels is further optimized,which can accumulate valuable experience for the promotion of BIM forward design in the tunnel specialty.
