Research on the Application of BIM Technology in CRTS Double-block Ballastless Track of Fuzhou-Xiamen Railway

结合福厦铁路BIM试点项目,将Dynamo可视化编程技术应用于铁路无砟轨道BIM设计中,阐述轨道BIM参数化设计思路和流程。针对项目特点,建立轨道部件自适应构件模型,采用Dynamo编程定义节点的逻辑关系。实践表明,该技术可提升CRTS双块式无砟轨道结构建模效率,提高设计质量,对类似应用具有推广和借鉴意义。

By leveraging the BIM pilot project on Fuzhou-Xiamen Railway,Dynamo visual programming technology is applied to the BIM design of the railway ballastless track,and the BIM parametric design ideas and process for the railway track are introduced.According to the characteristics of the project,the adaptive family model of track components is built,and the logical relationship of nodes is defined by Dynamo programming.The practice shows that the technology can improve the modeling efficiency of CRTS doubleblock ballastless track structure and improve the design quality.Therefore,it can be established as a model for similar applications.
