基于Revit的铁路线路三维信息平台开发

智能高铁是我国高速铁路发展的趋势,BIM技术融合智能化、信息化等手段,可实现铁路项目的全生命周期管理,提高管理水平和工作效率。根据BIM技术特点,基于Autodesk Revit建立铁路线路三维信息平台,为铁路项目信息化管理提供参考。首先,利用PowerCivil并根据线路平、纵断面等资料,生成线路中心线三维线形,为后续线路三维信息模型建立提供基础条件;随后,将线路中心线三维线形导入Revit平台,利用二维构筑物图纸创建各种构筑物族,再通过Dynamo编写命令将各种构筑物族沿线路里程布置,从而完成线路三维信息平台的构建。研究发现:三维信息平台可满足铁路线路模型三维可视化要求,并将铁路线路设计、施工、运维各阶段的信息进行融合,为铁路项目信息化管理搭建可操作的平台基础。

Development of Railway Line Three-dimensional Platform Based on Revit

Intelligence is the development trend of high-speed railway in China.BIM Technology integrates intelligence,information and other means,which can be used for the whole life cycle management of railway projects and both management level and efficiency can be improved.According to the characteristics of BIM technology,a three-dimensional information platform for railway project is established based on Autodesk Revit,which provides a reference for railway project information management.The three-dimensional railway center line can be generated from the horizontal and vertical section data using PowerCivil,which is the basement of the railway three-dimensional information model.By importing the 3D railway center line into Revit and developing various structure families using 2D design drawings,the railway 3D information platform can be established through arranging the various structure families along the center line using Dynamo.It is concluded that the railway 3D information platform can satisfy the requirements of 3D visualization,and the information of railway project design,construction,operation and maintenance procedure is integrated,which build a platform foundation for information management of railway projects.
