【摘要】 城市地下管线担负着运输能量、传输物质的重要任务,是城市赖以生存和发展的物质基础,被称为城市的“生命线”。随着城市扩建,城市物质流、能量流逐渐增大,城市地下管线的密集度和空间分布也随之急剧增大。原始落后的地下管线管理方式严重制约了城市经济发展,对社会稳定带来了隐患。随着GIS技术的不断发展,将GIS技术引入到城市地下管线管理应用中,能科学、完整、准确地描述城市地下管线的分布特征,并能为城市规划部门提供可靠的决策依据,实现了城市地下管线现代化、信息化的建设和管理。系统结合地下管网的分布特点,在收集整理原有数据基础上,利用空间数据库引擎ArcSDE将系统数据导入到Oralce9i数据库中,并采用强大的ArcEngine控件和Visual C# 2005集成技术设计开发了城市地下管线综合应用管理信息系统。系统主要研究内容分为以下几个方面:(1)根据地下管网的数据特点,对城市地下管线数据进行建模分析,得到最优的数据存储方式,包括空间数据库中存储数据内容、组织方式和存储机制;(2)围绕组件式GIS集成技术展开研究,重点研究ArcEngine和Visual C#2005集成开发方法,包括对各种地下管线的查询、检索和数据统计、显示、输出等功能的实现;(3)利用ArcEngine强大的空间分析功能,实现对地下管线的纵断面分析、横断面分析、水平净距分析、垂直净距分析和事故分析等。更多还原

【Abstract】 Urban underground pipeline charged with the important tasks of energy transportation and material transport, which is the material basis for city’s survival and development, is called the "lifeline" of city. With the expansion of cities, urban material flow and energy flow is increasing gradually; along with which, the intensity and spatial distribution of urban underground pipeline will also be dramatically increased. The original underground pipeline management has seriously hampered economic development in cities; brings in hidden dangers to the social stability. With the continuous development of GIS technology, introducing GIS technology to the urban underground pipeline management applications, will describe the distributions of the urban underground pipeline completely and accurately, and will also providing a reliable basis for decision making for urban planning departments, realizing the modernization and information for the construction and management of the city underground pipeline.The system combines the features of the underground pipe network distributions, based on the collection of the original data, importing data into the Oralce9i database by applying space database engine ArcSDE; designing and development of the city underground pipeline integrated application and management information systems by adopting the strong ArcEngine controls and Visual C # 2005 integrated technology. The research can be mainly divided into the following parts:(1) Obtaining the optimization data store mode through the modeling analysis of the urban underground pipeline data based on the data characteristic of the underground pipelines.(2) The study surrounding the component GIS integration technology, focusing on integrated development approach between ArcEngine and Visual C # 2005, including the query , retrieval, output and statistics of various underground pipelines, the realization of other functions.(3) Using the powerful spatial analysis functions of ArcEngine, realizing the functions of vertical section of the underground pipeline analysis, cross-sectional analysis, the level space analysis, vertical space analysis and accident analysis.更多还原
