摘要
研究目的:铁路工程数字化建模技术已经取得重大进步,但铁路工程数字化设计交付生态尚未形成.铁路工程包含多个专业领域,现有BIM设计软件对大体量多专业模型的集成效率低,且不易与其他软件进行数据交换,亟需对铁路BIM设计成果集成数字化交付技术开展研究.研究结论:(1)利用GIS对大场景与多源数据的支持,将BIM精细化设计成果与地理信息大场景进行融合,基于B/S模式开发了铁路BIM集成系统,降低了对终端用户设备的硬件要求;(2)该系统可从全局角度展示BIM设计成果,实现微观与宏观相结合的集成数字化交付,有效解决铁路工程信息传递问题;(3)该系统应用于广湛高铁400 km工程BIM设计成果集成以及设计检查与优化,发现问题22处,通过优化可为工程实施提供高质量的设计成果.
Research purposes:Significant progress has been made in the digital modeling technology of railway,but the ecosystem of digital design and delivery of railway has not yet formed.Railway engineering including many domains,the existing BIM software has low integration efficiency for large-scale and muli-disciplinary models,and it is not easy to exchange data with other software.Therefore,it is urgent to research on the integrated digital delivery technology.Research conclusions:(1)GIS can support large scene and multi-source data.Based on this,the integration of BIM and GIS was implemented and an integration system was developed using B/S mode reducing the hardware requirements for end users.(2)The system can visualize BIM design results from an overall perspective to realize integrated digital delivery combining micro and macro,and effectively solve the problem of railway engineering information transfer.(3)The system was used to integrate,check and optimize the design of Guangzhou-Zhanjiang high speed railway with 22 issues being found and the quality was improved.
