As a key component of urban geography information system , urbanintegrated underground pipe information system ( uiupis ) works as an exclusive tool to design , manage and assist policy decision 城市综合地下管网信息系统作为城市地理信息系统的重要组成部分是城市科学规划、管理和辅助决策等工作的重要工具。
They are essential for sustaining the normal operation of a community . after a destructive earthquake , the damage of the lifelines and the secondary disaster are more serious in modern cities 城市的规模越大，现代化建设的程度越高，在强烈地震袭击下，地下管网系统的地震破坏和由此产生的次生灾害也越严重。
In addition to an ample research on concerning national software and information material , this article discussed the establishment and application of spatial data model by adhering to practical design and research 本文结合昆明市综合地下管网信息系统设计和开发的实际工作，探讨了地下管网空间数据模型的建立和应用。
With the continuously expanding of the city and the rapidly developing of the municipal enterprises , the contradiction between the demand for scientific and efficient management of underground pipelines and the backward managing means at present is coming into focus 随着城市建设的不断推进和相关企业的快速发展,对地下管网进行科学有效管理的要求与目前落后的管理手段之间的矛盾日益突出。

Foundation construction issued by the ministry of construction , p . r . china . our operation includes research development , sales , installation . construction and after - sales service for air conditioner and ventilation engineering , together with its relevant facilities etc . electro - mechanic is one independent party from dasheng , we have one exellent heating ventilation engineers team and many professional installing building teams 在软件开发方面主要从事地理信息系统和图文办公自动化方面的基础平台与应用系统开发，并以城市地下管网信息系统见长，是国内率先从事该领域软件开发的公司之一，尤其是在自来水煤燃气通信交通以及城市综合管网行业占有优势。
So , it is necessary to study the seismic reliability of lifeline systems for the needs of earthquake hazard mitigation . this paper presents some methods for solving these problems , which is based on the fact in our country . the main contents includes : 1 ) the seismic damage behavior of the buried pipeline is analyzed by synthesis 对此，本文从我国城市抗震防灾工作对基础性研究的迫切需要出发，结合我国城市地下管网系统的实际情况，在综合分析了现有国内外相关研究的基础上，以理论探讨和工程实用性并重，对城市地下管网系统的地震可靠性分析方法进行了较为全面系统的研究。
The city underground pipelines gis is a multi - functional computer system , which is able to make the search of geographic data and relative attributes together in addition to serving as enquiry system by presenting the information both in character and graphic simultaneously . this system changes manual model that was used widely before and realizes the scientific and automated 城市地下管网地理信息系统是构建在计算机的软硬件平台上,将文字信息与图形描述结合起来,实现了空间地理数据和相关属性数据的共同检索和相关查询的综合系统,改变了过去手工管理的模式,可以实现管理的科学化和自动化。
