宁淮高铁轨道BIM设计应用

Application of BIM in the Track Design of Nanjing-Huai’an High Speed Railway

为探索和加快研究落实铁路轨道工程数字化,在宁淮高铁轨道工程设计中进行了BIM技术应用,基于专用轨道BIM设计软件进行了快速建模和设计成果交付。基于创建的轨道模型,实现了轨道工程与线下基础之间的接口检查及优化、轨道工程数量自动统计、轨道工程二维图纸输出和无砟轨道关键施工数据提取等应用,在保证BIM设计效率的同时取得了满意效果,交付成果满足轨道设计和铁路行业BIM相关标准要求。铁路轨道工程BIM技术应用方法具有普遍适用性,可在高速铁路、城际铁路、客货共线铁路以及城市轨道交通等轨道设计中推广使用。

In order to promote the research and implementation of digitalization of railway track engineering,BIM technology was applied in the track design of Nanjing-Huai’an HSR, and rapid modeling and design results were delivered based on the BIM design software for dedicated track. In accordance with the track models, interface inspection and optimization between track engineering and substructure, automatic statistics of track engineering quantity, output of two-dimensional drawings of track engineering, as well as extraction of key construction data of ballastless track were applied. Satisfactory results were achieved while BIM design efficiency was ensured, and the deliverables met the requirements of relevant BIM standards of track design and railway industry. The application method of BIM technology in railway track engineering is generally applicable, which can be promoted in the track design of high speed railway, intercity railway, mixed passengerfreight railway and urban rail transit systems.
