基于BIM的铁路隧道附属洞室设计研究与应用

为升级设计手段，提高设计质量，实现铁路工程数字化交付，文章以铁路隧道附属设施设计为切入点，通过梳理设计流程、研究优化技术，提出基于建筑信息模型（BIM,Building Information Modeling）的铁路隧道附属洞室设计方法。配合BIM软件的二次开发，该设计方法能有效打通隧道设计上下游数据，显著提升隧道设计智能化水平。实践证明，基于该方法在Bentley平台下开展附属洞室设计，能同时满足项目BIM交付及现有设计规范下二维图纸交付的需要，提升附属洞室设计的效率和质量，实现BIM技术与传统设计的融合，助力铁路行业从BIM辅助设计到BIM正向设计的转变。

Design of railway tunnel auxiliary cavern based on BIM

In order to upgrade the design means, improve the design quality, and realize the digital delivery of railway projects, this paper took the design of railway tunnel ancillary facilities as the starting point, and proposed a design method of railway tunnel ancillary chambers based on Building Information Modeling(BIM) by combing the design process and studying optimization technology. With the secondary development of BIM software, this design method can effectively get through the upstream and downstream data of tunnel design and significantly improve the intelligent level of tunnel design. Practice has proved that the ancillary chamber design based on this method under Bentley platform can meet the needs of project BIM delivery and 2D drawing delivery under existing design specifications, greatly improve the efficiency and quality of ancillary chamber design, achieve the integration of BIM technology and traditional design, and help the railway industry to transform from BIM aided design to BIM positive design.
