摘　　要：穿越复杂艰险山区轨道交通线路的勘察设计工作面临诸多难点,尤其是线站位方案的确定依赖于常规勘测手段,在工期紧张的情况下很难高效地完成设计工作。为提升山区轨道交通工程勘察设计效率,依托重庆市郊铁路永川线工程开展基于BIM+GIS电子沙盘的三维设计研究与应用,更新了系统化、数字化的三维设计手段。阐明了BIM设计组织实施流程和地质BIM建模方法,提出电子沙盘系统总体技术架构,以Skyline为基础平台搭建BIM+GIS电子沙盘,通过数据格式转化和地形文件编辑解决了BIM模型与GIS数据融合剖切问题,利用线路三维中心线函数的参数联动机制实现了设计方案实时更新展示功能。研究成果在永川线应用表明:通过BIM+GIS电子沙盘可以高效完成三维场景下建筑方案优化、管线综合与碰撞检查、景观分析与线站位比选等关键设计环节,满足永川线工程设计进度和精度要求,有效缩短工程项目设计周期,提升工程建设效率,可为山区市郊铁路三维设计提供参考。The survey and design work of railway transit line crossing complicated and difficult mountainous areas has a lot of difficulties.In particular,the determination of the line and station location plan relies on conventional survey methods for a long term.It is difficult to efficiently complete the design work within a limited construction period.To improve the survey and design efficiency of railway transit projects in the mountainous area,three-dimensional design research and application based on BIM+GIS electronic sand table is completed relying on the Yongchuan line project of Chongqing suburban railway and the systematic and digital 3D design means are updated.The organization and implementation process of BIM design and geological BIM modeling method is illustrated,the overall technical architecture of the electronic sand table system is proposed.BIM+GIS electronic sand table is built with Skyline as the basic platform,the problem of fusion and sectioning of BIM model and GIS data is solved through data format conversion and editing of terrain files,and the function of real-time update and display of the design scheme is realized by using the parameter linkage mechanism of the three-dimensional center line function of the line.The application of research results on the Yongchuan line indicates that BIM+GIS electronic sand table can efficiently complete key design links such as building scheme optimization,integration and collision detection of pipeline,landscape analysis,and comparison and selection of line and station location in the threedimensional scenes,which meet the requirements for engineering design schedule and accuracy of the Yongchuan line,effectively decrease the design cycle of the engineering project,improve the engineering construction efficiency,and provide reference for the three-dimensional design of suburban railway in mountainous areas.
