摘　　要：本文提出基于BIM+GIS三维协同设计系统的保通设计方案,在G85G76成渝改扩建高速公路项目中落地应用。成渝高速交通量大,地方道路、快速路、既有高速交叉等路线多,改扩建阶段保通和施组难度高。三维协同设计系统保通设计方案利用BIM+GIS数据集成性强、直观形象还原真实场景、模拟分析保通设计;设计阶段,施工单位可提前介入基于可视化成果进行保通方案汇报,尽早发现问题,较于传统平面保通设计大幅提升工作效率和设计质量,为后期施工阶段保通方案落地实施提供了可靠保障。This article proposes a road-keeping-open-to-traffic design scheme based on the BIM+GIS three-dimensional collaborative design system,which was implemented in the G85G76 Chengdu-Chongqing Expressway Reconstruction and Expansion Project.The Chengdu-Chongqing Expressway has a large traffic volume and a large number of local roads,expressways,existing expressway intersections,etc.,making it difficult to ensure access and construction during the reconstruction and expansion phase.The three-dimensional collaborative design system-based road-keeping-open-to-traffic design plan uses BIM+GIS data to have strong integration,intuitive images to restore real scenes,and simulate and analyze the road-keeping-open-to-traffic design;during the design stage,the construction unit can intervene in advance to report the road-keeping-open-to-traffic plan based on visual results,so as to identify problems as early as possible.Compared with the traditional planar protection design,the work efficiency and design quality are greatly improved,which provides a reliable guarantee for the implementation of the protection plan in the later construction stage.
