基于BIM+GIS的灌区工程可视化研究

Research of irrigation project visualization based on BIM+GIS

传统灌区工程管理可视化程度低,难以形象、直观地掌握工程管理动态信息。应用工程领域新兴的BIM+GIS技术,依托于甘肃省古浪县黄花滩调蓄供水工程信息化建设项目,构建了灌区建筑物及各种设备的BIM模型,融合灌区实景模型及正摄影像等GIS数据,实现了灌区工程的可视化展示。运行实践表明:该项目的可视化应用提升了工程建设、运行、维护管理的精细化程度,加强了统一可视化平台下的信息交流和沟通以及业务数据的共享和分析,为灌区管理提供了高效、直观的信息服务。

The visualization degree of the traditional irrigation project management is low,so grasping its dynamic information of the management vividly and intuitively is difficult.The emerging BIM+GIS technology in the engi⁃neering field in recent years was employed to construct BIM models of buildings and various equipment for Huang⁃huatan Reservoir and Water Diversion Project in Gulang County of Gansu Province,and the visual display of the ir⁃rigation district was realized through integrating GIS data such as the real scene model and forward photo.The prac⁃tice showed that the visual display of the irrigation district had improved the operation efficiency and fine manage⁃ment,strengthened the information communication and the share and analysis of data under the unified visual plat⁃form,which has provided the irrigation district with efficient and visual service.
