随着城市燃气管网的飞速发展,在役燃气管道的安全问题日益突出,针对燃气事故致因及后果,基于ArcGIS网络模型,运用GIS网络拓扑分析、空间数据库等技术,设计利用管网网络模型实现管网事故分析方法,并结合C#+ArcEngine编程技术实现燃气管网事故分析模块,该模块实现爆管分析、燃气泄漏扩散范围分析、最优路径分析、连通性分析等功能。实践证明,该模块的功能实现燃气管网事故可视化预警分析,并由燃气管网网络分析结果,提供事故应急预案,为应急抢险提供数据和技术支持。
With the rapid development of urban gas pipelines, the safety problems of gas pipelines in service have become increasingly prominent. According to ArcGIS network model, GIS network topology analysis and spatial database technology are used to design and utilize the network model Realize the analysis method of pipe network accident, and combine the C # + ArcEngine programming technology to realize the accident analysis module of gas pipe network. The module realizes the functions of pipe burst analysis, gas leak diffusion range analysis, optimal path analysis and connectivity analysis. Practice has proved that the function of this module realizes the visual warning analysis of gas pipeline accident, and provides the accident emergency plan based on the result of gas pipeline network analysis to provide data and technical support for emergency rescue.
