【摘要】 论文首先介绍了城市地理信息系统的概念和发展现状,指出城市地下管网地理信息系统是城市地理信息系统的重要组成部分,分析了当前城市地下管网管理的现状,阐明了GIS技术应用于城市地下管网管理的必要性和优越性,通过对当前主要城市地下管网地理信息系统的分析研究,提出了论文研究的主要内容。地下管网数据预处理与数据库设计是建立地下管网综合地理信息系统的前提和基础,论文首先介绍了管网数据预处理的内容和方法。空间数据库设计是地下管网综合地理信息系统开发设计的核心。针对当前大多数地下管网地理信息系统基于文件-关系数据模型的系统设计在管网空间分析方面的不足,论文采用面向对象的数据模型设计方法,提出了一个实用的面向对象的综合地下管网数据模型,在此基础上,采用对象-关系型数据库Oracle的空间数据库组件Oracle Spatial,实现对地下管网空间数据和属性数据的一体化管理,并实现了综合地下管网的数据结构设计。论文重点研究了城市地下管网综合地理信息系统的总体设计和功能模块设计与实现。论文对系统用户需求进行了分析,论述了系统的设计原则、目标、开发方式和开发平台,在此基础上,完成了系统总体结构设计和图形显示编辑、查询、断面分析、空间量测、统计报表打印、三维显示等具体功能模块的设计与实现。爆管分析是地下管网GIS中重要的空间分析功能之一,论文论述了爆管分析的主要任务,阐述了爆管分析的理论模型,分析了树状管网中结点的父结点、子结点的性质,实现了管网的阀门拓扑关系的分析,在此基础上,完成了地下管网爆管关阀分析的算法实现。最后给出了一个给水管网关阀分析的应用实例。最后,对论文的主要工作进行了总结,对需要进一步深入研究的内容提出了自己的设想。更多还原

【Abstract】 This thesis introduces the concept and the present development condition of the urban geographic information system first, and points out that the urban underground pipeline network GIS is an important part of urban geographic information system. This thesis analyses the current management actuality of underground pipeline network, and clarifies the necessity and the superiority that applying GIS technique to the management of urban underground pipeline network. According to the analytical and research on the current main urban underground pipeline network comprehensive GIS, puts forward the main contents of the thesis research.The underground pipeline network data pretreatment and the database design are the premise and foundation of building up the underground pipeline network comprehensive GIS, the thesis introduces the contents and method of the pipeline network data pretreatment first. Spatial database design is the core of the development and design of underground pipeline network comprehensive GIS. Most of current underground pipeline network use file-relation data models, for those shortages that these models have in network spatial analysis, the paper develops an object-oriented data model design method, and puts forward a practical object-oriented comprehensive underground pipeline network data model, on the basis of which, the paper realizes the integrative management of the spatial data and property data of underground pipeline network and the design of comprehensive underground pipeline network data structure by means of using the spatial database component Oracle Spatial of the object-object database Oracle.The thesis focuses on the overall design of the urban underground pipeline network comprehensive GIS and the design and implementation of the function modules. The thesis discusses the principle and target of system overall design, and then completes the system total structure design, graphic display, edit, search, section analysis, spatial measurement, statistical forms output, 3D display and so on according to the system total target, the design principle and the customer demand.Analysis of pipe burst is one of the important spatial analysis functions of underground pipeline network comprehensive GIS, the thesis puts forward the main assignment of pipe burst analysis, and analyzes the character of the usher nodes and the retral nodes of arborescent pipe network. The paper realizes the valve topological analysis of the pipe network. Then the paper completes the algorithm implementation of the pipe burst shutdown valve. At last , an example is given.In the end, the author sums up the main work of the thesis and puts forward the work need to do in the future.更多还原
