摘要
研究目的:当前BIM技术在轨道工程设计阶段的应用主要表现为依靠不同商业平台实现轨道三维模型的创建,因缺乏通用的软件平台及轨道工程专业模块,易出现零构件模型重复创建、相关专业变更引起的轨道BIM重复设计、模型与数据精度难以满足需求、曲线超高表现困难等问题,因此研发基于BIM技术的轨道三维数字化设计系统,促进轨道BIM正向设计及协同设计。研究结论:(1)结合BIM技术与铁路轨道工程结构特点,以数据驱动方式构建了铁路轨道三维数字化设计系统;(2)根据线路、路基、桥梁、隧道等相关专业信息与轨道设计信息,创建了轨道工程数据模型,以商业BIM软件为图形引擎,实现了零构件模型的参数化创建以及轨道BIM模型的快速生成;(3)系统促进了专业间协同,解决了因线路、桥梁、隧道等相关专业变更引起的轨道重复建模等问题,有效提高了轨道三维数字化BIM模型创建的效率和精度;(4)经验证,研究成果初步实现了轨道工程BIM正向设计,可为铁路轨道BIM设计与深化应用提供技术支撑。
Research purposes:At present,BIM technology is applied in the design stage of track engineering to create 3 D track model based on different commercial platforms.Due to the lack of general platform and specialized modules in track engineering,there are some problems such as repeated creation of the component model,repeated design of the track model due to the change of related engineering,difficulty in meeting the requirements of model and data precision,and difficulty in the performance of ultra-high curve,so this paper studies railway track 3 D digital design system based on BIM to promote multi-professional collaborative design.Research conclusions:(1)Combined with BIM technology and the characteristics of track engineering structure,the 3 D digital design system of railway track is build by data-driven.(2)According to the information of the alignment,earthworks,bridge,tunnel and the track design information,the data model of the track engineering is created.With the commercial BIM software as the graphics tools,the parametric component model and the track BIM model are created.(3)The system promotes collaboration of related engineering,solves the problem of repeated creation of track model which caused by the change of related engineering,such as alignment,bridge and tunnel,and effectively improves the efficiency and accuracy of track BIM model.(4)It has been proved that the system preliminarily realize the BIM design of track engineering,which can provide technical support for the BIM design and further application of railway track.
