针对城市地下管线信息管理过程中涉及数据复杂、隐蔽等特点，将GIS引入地下管线信息管理中，搭建了基于组件式GIS的城市地下管线综合信息系统应用框架。分析了使用ArcEngine集成技术在城市地下管线综合应用过程中的优势，探讨了利用GIS集成技术在城市地下管线数据集成、信息采集、信息处理及空间分析等一系列操作过程。系统采用Visual C# 2005与ArcEngine集成技术和Oracle 9i数据库平台，运用ArcSDE空间数据库引擎综合应用开发，不仅能够充分发挥GIS的矢量数据对城市地下管网分布情况的编辑、管理、分析等功能，还能够对地下管网受损受害地点的快速、精确定位管理具有一定的应用参考价值。
The urban underground pipeline information system is based on the technology of GIS, considering the pipeline characteristics with respect to the data complexity and hiding. The application framework is built on COMGIS, and the advantage of the information system for the urban underground pipelines based on ArcEngine is analyzed. The integration technology of GIS is used for the operating procedure in the data integration, information collection, information disposal and spatial analysis. The integration technology of Visual C# 2005 and ArcEngine is combined with the database of Oracle 9i database by applying ArcSDE. The system provides the function of spatial information extracting, processing, management, inquiry and statistical analysis, for professional information and spatial information with respect to underground pipelines, and for accurate positioning and dynamic management of underground pipeline data.
