摘要
以BIM模型为数据源进行铁路桥梁纵断面二维出图面临一些问题:在平曲线范围如何以里程为横坐标沿线位展开BIM模型;如何从三维数据服务获取地形数据用于图纸绘制;如何从地质BIM模型高效提取绘图所需的几何与非几何信息。针对上述问题,本文基于BIMBase国产自主三维图形平台,首先采用实例属性解译技术提取桥梁主体结构信息,其次分别研究铁路工程地形计算服务和铁路工程地质成果数据服务,动态接入远程服务接口以提取地形、地质信息,最后调用AutoCAD/API函数开发桥梁纵断面出图软件,并在广湛高铁完成工程实际应用。本文的研究方法和开发思路可为其他工业软件国产化及BIM技术研发项目提供借鉴。
There are three main problems in using BIM model as data source for two-dimensional railway bridge longitudinal profile drawing:(1)how to unfold BIM model along alignment with mileage as horizontal axis including horizontal curve zone;(2)How to obtain terrain data from 3D services for drawing;(3)How to efficiently extract geometric and non-geometric information required for drawing from geological BIM models.To solve the above problems,based on the BIMBase domestic 3D graphics platform,this paper first uses instance attribute interpretation technology to extract main structure information of bridge,then develops railway engineering terrain and geology data service systems respectively,dynamically connects to remote service interfaces to extract the terrain and geological information,finally calls AutoCAD/API functions to develop bridge longitudinal profile drawing software,and completes application in Guangzhou Zhanjiang High speed Railway project.Research methods and development ideas in this paper can provide reference for other industrial software localization alternatives and BIM technology R&D projects.
