城市地下管线信息系统的建立与应用

本文以广州市建立综合性地下管线信息系统为背景,针对中国城市地下管线勘测与管理的现状,提出了地下管线普查与信息系统建立的实施流程,强调了数据源保证、标准化质量监控、实时更新等关键技术问题.实现了“普查成图与监理入库相结合、全面普查与竣工测量相结合、规划审批与现状信息相结合”的建立具有空间决策支持系统或专家系统雏形的综合性管线信息系统模式,该模式适用于管线历史资料不完整、精度不高的发展中国家的广大城市.

The Establishment and Application of Urban Underground Pipeline Information System

On the basis of the experience of developing Guangzhou Urban Pipelines Information System (GUPIS),the authors put forward a set of theories and methods about establishing a comprehensive underground pipeline information system of large cities in China. In their implement schema, three elements including data source, standard quality check and real-time data updating are emphasized. A system model, as the authors will discuss, has been well practiced in establishing a comprehensive pipe and cable information system with Spatial Decision Support function and comprehensive analysis capability supported by Expert System.This system is established by combining overall surveying and mapping with supervision and database building, combining overall general survey with completion survey and combining planning approval with current information. This model has been proved to be suitable for developing comprehensive urban underground pipeline information system in large cities of developing countries where there are incomplete and imprecise pipeline data.
