基于BIM标准体系的铁路协同设计体系研究

随着物联网、云计算、大数据等前沿技术的不断进步,铁路行业正在迎来新的发展机遇。数字孪生铁路是以智能建造、智能装备、智能运营为核心的智能高铁技术应用数字环境,也是铁路工程全生命周期应用的数据基础。传统的设计方式中各专业内和专业间数据相对离散、逻辑关联性不高、成果不易维护且信息存在大量冗余,无法满足铁路智能化应用的要求。以京张客运专线BIM项目为载体,研究能够集中管理各专业设计资源、定制各专业设计参数交互流程、构建专业间数据层面逻辑关联、具有统一数据框架的协同设计体系。该体系强化了各专业间的联系,提升了设计质量,为工程数字化建设提供了数据结构组织有序、易于维护、动态可感知的数字孪生工程,同时也为勘察设计企业拓展工程全生命周期业务提供了可靠的技术保障。

Research on Railway Collaborative Design System Based on BIM Technical Standard System

With the development of cutting-edge technologies such as the internet of things,cloud computing and big data,the railway industry is embracing new development opportunities.Digital twin railway is the digital environment for the application of intelligent high-speed railway technology,and it is also the data basis for the application of railway engineering in life cycle.In the traditional design method,the result data are relatively discrete with low logical correlation,difficult to maintain and containing massive information redundancy,which cannot meet the requirements of intelligent railway application for data.Based on BIM implementation of Beijing-Zhangjiakou High-speed Railway,we found the solution to construct the collaborative design system which can be used to centrally manage various professional design resources,customize the interactive process of various professional design parameters,build data logical relationship and adopt unified data framework.It also strengthens the connection between various disciplines,improves the quality of the design,provides the easily maintainable,dynamic and perceptible digital twin project with orderly data structure for the digitization construction of engineering,and provides reliable technical support for survey and design enterprises to expand the business of engineering for its whole life cycle.
