摘  要:
给水管网是城市给水系统重要的组成部分,其可靠运行对整个给水系统充分发挥经济效益和社会效益起着举足轻重的作用。对现有的给水管网设计、水力计算中的管网模型进行了综合的分析研究,基于某些合理假定,并在系统可靠性分析中详细考虑了阀门的配置作用,进而提出了一种新的管网简化模型:环节-阀门表示方法,可用于系统可靠性初步分析及期望缺水量计算,最后通过算例分析,进一步证明了该方法对指导维修人员的行动有一定的参考作用和实用价值。

摘  要:
Through comprehensive research on the existing pipeline net models for design and hydraulic calculation of water supply pipeline net,based on several reasonable hypothesis,considering the configuration effect of valve in reliability analysis,a new kind of pipeline net simplified model for water distribution system,namely valve-segment method,was proposed in this paper.This method can be used in the preliminary reliability analysis and calculation of expected water scarcity quantity.The example analysis showed that the method had some reference value to the practical repair,too.
