基于BIM技术的铁路工程智能校审与数字认证

Intelligent Verification and Digital Authentication of Railway Engineering Based on BIM Technology

近年来,BIM技术在铁路行业落地应用进入快速发展时期。三维信息模型准确性、与二维图纸一致性以及合规性等无法保证成为制约铁路行业BIM技术应用发展的主要障碍。结合西十高铁和酒额铁路项目案例,分析并提出BIM模型的完整性、一致性和合规性解决方案:正向设计、智能校审和数字认证。后续开展深入应用,从理论和实践上验证该方案的可行性和必要性。结果表明:(1)BIM正向设计是保证模型准确性、与二维图纸一致性的首要技术措施;(2)智能校审是保证模型准确性、合规性的必要技术手段;(3)数字认证为BIM技术在工程全生命周期应用奠定基础。研究成果对进一步提高铁路信息化建设和BIM技术推广,具有一定借鉴和应用价值。

In recent years,the application of BIM Technology in the railway industry has entered a period of rapid development.The accuracy,consistency with 2D drawings and compliance of 3D information model cannot be guaranteed,which has become the main obstacle restricting the application and development of BIM Technology in the railway industry.Combined with the cases of Xian-Shiyan High-speed railway and Jiuquan-Ejina Railway project,this paper analyzes and puts forward the solution of BIM integrity,consistency and compliance:forward design,intelligent verification and digital authentication.Follow-up in-depth application,to verify the feasibility and necessity of this scheme in theory and practice.The results show that:(1)BIM forward design is the primary technical measure to ensure the accuracy of the model and the consistency with 2D drawings;(2)Intelligent Verification is a necessary technical means to ensure the accuracy and compliance of the model;(3)Digital authentication lays the foundation for the full life cycle application of the projects。The research results have certain reference and application value for further improving railway information construction and BIM Technology Promotion.
