摘　　要：为了解决铁路桥梁BIM应用过程中出现的重复建模、各阶段数据传递不畅的问题,对铁路桥梁BIM模型的建模方法和管理方法进行研究。提出了单一模型入口、多文件描述的建模方法,对工程各阶段的模型进行有效组织,避免了重复建模,实现了模型跨阶段应用。提出了文件和数据两级的管理方法,解决了BIM模型各阶段间和专业间的信息传递问题,实现了数据级的信息传递和共享,为协同设计提供了切实有效的方法。结合京张高铁等铁路工程项目,介绍了协同设计基础环境的搭建、数据级协同设计方法的应用、参数化设计到智能设计的实现、模型仿真分析及应用。单一模型入口、多文件描述的建模方法及文件和数据两级管理方法为BIM模型的全生命周期协同和应用提供有效的实现路径,可为后续BIM技术在铁路桥梁工程中的应用提供借鉴。The modeling and management methods of railway bridge BIM models are studied to solve the problems of repeated modeling and poor data transmission between project phases.A modeling method with single model entry and multi-file description is proposed,which effectively organizes the models in each phase of the project,avoids repeated modeling,and realizes cross-phase application of the model.A two-level file and data management method is proposed,which solves the problem of BIM model information transmission between phases and between disciplines,fulfills data-level information transmission and sharing,and provides a practical and effective method for collaborative design.With reference to the Beijing-Zhangjiakou high-speed railway and other railway engineering projects,this paper introduces the construction of the collaborative design basic environment,the application of data-level collaborative design methods,the realization from parametric design to intelligent design,model simulation analysis and application.The modeling method with single model entry and multi-file description and the two-level file and data management method provide an effective way for full life cycle collaboration and application of BIM models,and offer some references for subsequent application of BIM technology in railway bridge engineering.
