铁路站场BIM技术应用研究

Research on BIM Technology for Railway Station

BIM技术应用是一次设计手段的变革,站场专业是铁路工程中的龙头专业,是BIM技术应用的重点专业,站场设计的效率和质量对整个铁路的建设和运营具有极其重要的影响。论述站场专业BIM技术应用现状。以站场专业利用BIM技术作为设计手段为目的,从设计软件、标准、基础数据和交付平台等方面对站场专业BIM技术应用提出解决对策;提出站场BIM设计软件研发的两种方法。以铁路工程信息模型分类和编码标准为基础对站场IFD标准进行扩充和完善,以站场和航测专业的数据接口为例对站场设计从二维到三维转变时的接口数据适应性调整进行说明。通过对站场设备添加可定位的身份编码,在自主研发的BIM综合管理平台上构建铁路站场专业三维信息模型组织结构树。

The application of BIM is a change of design methodology. Railway station design is the key point of railway engineering and BIM application. The efficiency and quality of railway station design have an extremely important influence on the construction and operation of the whole railway engineering. This paper discusses the present situation of BIM for railway station. In order to make full use of BIM technology as a design tool, countermeasures and suggestions from the aspects of design software, standards, basic data and delivery platform are put forward. This paper also proposes two methods of developing BIM design software for railway station, expands and perfects the IFD standard of rail station based on classification and coding standards of railway information model, and explains the adaptability adjustment of interface data of railway station. By adding ILD to information model, this paper constructs the organizational structure tree of the railway station information models on the BIM integrated management platform.
