基于BIM技术的铁路工程正向设计方法研究

Research on Forward Design Method of Railway Engineering Based on BIM Technology

铁路工程BIM设计相比建筑工程具有涉及专业多、专业接口复杂、与地形地质关系密切的特点。在现阶段,由于专业间BIM资源不能很好地相互利用,铁路工程BIM仍以单专业翻模为主,各专业开展BIM正向设计困难。对此情况,选取银西高铁项目为研究试点,以本特利平台系列软件为基础,按照铁路工程设计一般流程,探索研究基于BIM技术的铁路工程正向设计技术路线。提出一种铁路工程BIM设计协同管理和正向设计方法,并对铁路BIM标准进行初步应用,为今后开展铁路工程全专业BIM设计提供借鉴。

Compared with architecture engineering,the design of railway BIM is unique for its features,such as multi specialties,complex interface and closer relation with topography and geology. Presently,because the BIM resources cannot be utilized well among specialties,the railway engineering BIM is still based on single specialty model,which makes it difficult to carry out forward design of all specialties. In this case,Yinchuan-Xi＇an High Speed Railway project is taken as the pilot. Based on Bentley platform software,this paper conducts research on railway engineering BIM forward design according to the general design process of railway engineering. Finally,the method of railway BIM collaborative management and forward design is put forward and railway BIM standards are preliminarily applied,which may provide references for future BIM design of all railway specialties.
