| 摘 要： | 利用WebGIS技术建立了爆管事故关阀分析系统,深入研究了管网要素之间的网络拓扑关系,分析了基于邻接表存储结构的爆管事故关阀分析流程,得出了爆管事故状态下的最优关阀方案和受影响管段.以某供水管网为例,实现了爆管事故时的关阀分析.该系统的建立大大降低了爆管事故造成的经济损失,提高了供水企业的现代化管理水平.

| Abstract: | To pipe burst happened frequently in a urban water distribution network,a system of WebGIS-based valve closing analysis in the pipe burst emergency was established.The topology relationship of water distribution network was thoroughly researched based on the adjacency list saving structure,and the process of implementation of valve closing analysis in the pipe burst emergency was described in detail.The optimal valve closing scheme and influenced pipe were obtained.The system was used in one water supply ne... |
