BIM技术在西韩城际铁路等三条陕西城际项目中的应用研究

Application of BIM in Three Intercity Projects in Shaanxi,Such as Xihan Intercity

近年来,在铁路BIM联盟推动下,铁路行业BIM技术发展迅速。但是由于受铁路行业自身特点的影响,铁路工程BIM技术应用尚未完全成熟。为促进BIM技术在铁路工程中的推广及应用,以陕西3条城际铁路BIM技术应用为案例,对铁路行业BIM技术应用面临的三维信息模型的高效构建、铁路BIM标准的应用、信息的交付与传递等难题进行研究。从铁路行业专业BIM软件的研发、铁路项目BIM标准的建立和完善、BIM综合管理平台的研发等方面对铁路工程BIM技术应用面临的难题提出解决对策。研发适用于铁路各专业的辅助设计软件。编制城际铁路BIM设计应用指南和设计成果交付标准,利用LID编码构建铁路辅助设计各专业结构树,并对铁路联盟IFD标准进行扩展和完善。研发BIM建造管理平台,为设计成果交付和施工阶段的BIM技术应用提供了基础。

Driven by the China Railway BIM Alliance,BIM technology in railway industry has developed rapidly in recent years.Influenced by the characteristics of railway industry,the application of BIM technology in railway engineering is not yet fully mature.In order to promote the application of BIM technology in railway,this paper,with reference to the application of BIM technology of three intercity railways in Shaanxi,studies the challenges faced in the application of BIM technology in railway industry:the efficient construction of 3 D information model,the application of railway standards and the submission and transmission of information.From the aspects of the development of BIM software for railway industry,the establishment and perfection of BIM standards for railway projects,and the development of BIM integrated management platform,this paper puts forward solutions to the problems encountered in the application of BIM technology for railway projects.The aided design software suitable for railway is developed.The BIM application guides for design and delivery standard of intercity railway are compiled,and the structure tree of railway is constructed by LID code.The IFD standard of railway BIM Alliance is expanded and improved.BIM management platform is developed,which provides the foundation for the delivery of design results and BIM application in construction stage.
