摘　　要：传统地下管线数据库多采用二维+三维的形式组织,二维管线数据通过空间数据引擎存储在文件或关系型数据库中,三维管线数据则多以文件型进行存储,应用时通过SDK接口关联ID实现二三维联动、分析,并不能真正做到二三维一体化。本文在充分分析管线二三维一体化数据、应用需求的基础上,基于地图符号化思想,研究出一套适合城市地下管线二三维一体化存储、更新、展示、应用的数据库设计,为城市地下管线数据库建设提供参考。The traditional underground pipeline database isnormally organized by the form of 2D plus 3I）. The 2I） data through the spatial data engine are stored in file or relation- ship database, 3D data are slored in file. Program code, through the SDK interface correlation ID. realizes the 2D and 3D linkage and analysis, hut not the integration of 2D and 3D . Based on the deep analysis of pipe 2D and 3D integra tion data and application requirements, with the idea of GIS map symbolization, this paper puts forward a set of database design that is suitable for pipe 2D and 3D data integration storage, update, display and application. It also provides reference for construction of urhan underground pipeline da tabase.
