摘　　要：本文针对影响比较严重的城市地下管线爆管问题,以城市供水管网的爆管问题为例,根据城市供水管网的数据特点,利用GIS技术建立了城市供水管线逻辑算法模型,并与广序优先遍历算法相结合,建立了考虑管线流向性的城市供水管线爆管分析优化算法。这一算法可以快速、有效地确认最佳关阀位置,减少了城市供水管线爆管事故处理时间和影响程度。Accidents of urban underground supply-pipe occur frequently, cause serious results, and seriously influence the development of a city and people＇s lives and property. How to reduce the damage caused by accidents of urban underground supply-pipe are attended by every city. This paper chose the problem of pipe burst for urban underground supply-pipe as case study and took the problem of pipe burst for water supplying network as an example, according to the data characteristics of urban water supplying network, a logic algorithm model was developed based on GIS and an optimized algorithm for urban water supplying network considering the network flow was developed based on the breadth first search algorithm. This algorithm can help to determine the correct valve needed to be taken off effectively, and the dealing time and influence degree of pipe burst accidents for water supplying network are reduced.
