Data Model for the Realization of Long-Distance Pipeline Integrity Management and Its Application
长输管道完整性管理GIS数据模型研究

Along with the constant development and expansion of the industry of long-distance pipeline construction in China,pipeline security has gradually become a focus of the country and the whole society.In view of this,some experts proposed pipeline integrity management combined with techniques of GIS,which has been considered as a well-adapted solution.In this approach firstly it needs data modeling and then all data such as pipeline design,as-constructed,inspection data,et al.are altogether and efficiently managed within defined spatial database.In this paper,the author first compares several worldwide currently existing pipeline data models,and then explains in detail the designing process of the long-distance pipeline data model that suits our pipeline industry,referring to the international pipeline integrity management theories and methods as well as domestic practical experience.Finally,the author elaborates the whole process of establishing the pipeline integrity management information system by dint of techniques of geographic information system and spatial database.In the latter process of model application,the pipeline integrity management information system is established then,which makes full use of all types of information provided by the data model and successfully develops the LineLoop management module,risk / integrity evaluation module and site management module.Practice has proved a high potential for applications of this proposed pipeline data model in China pipeline integrity management.
