铁路工程BIM协同设计与构件共享研究

建筑信息模型（BIM, Building Information Modeling）的广泛应用能够提升铁路工程建设技术水平以及信息管理的能力，也是铁路工程建设信息化的核心和方向，对铁路工程建设有着巨大的发展潜力和应用价值。BIM设计作为BIM全生命周期的源头，对BIM技术的推动起着至关重要的作用。立足于铁路工程建设项目设计阶段，对基于BIM的协同设计所涉及的工作流程及构件复用问题进行研究，提出了BIM模式下的协同设计流程以及BIM模型构件库方案，提高了BIM模型修改、维护的效率和便捷性，实现了设计资源的共享和利用，为建立BIM设计协同管理和正向设计体系奠定基础。

Collaborative design and component sharing of BIM in railway engineering

The wide application of Building Information Modeling(BIM) can improve the technical level of railway engineering construction and the ability of information management. It is also the core and direction of railway engineering construction informatization, and has great development potential and application value for railway engineering construction. As the source of BIM life cycle, BIM design plays an important role in promoting BIM technology. Based on the design stage of railway engineering construction project, this paper studied the workflow and component reuse of BIM based collaborative design, proposed the collaborative design process under BIM and BIM component library scheme, which improved the efficiency and convenience of BIM modification and maintenance, implemented the sharing and utilization of design resources, and laid a foundation for the establishment of BIM design collaborative management and forward design system.
