摘　　要：城市供水管网是生命线工程的重要组成部分,本文在研究团队系列成果的基础之上,从供水管网的地震反应分析入手,进一步修正了供水管网的渗漏分析模型,在瞬变流分析的基础之上,实现了带有渗漏特性的供水管网实时动态功能分析,建立了适用于地震时的供水管网实时动态功能分析的物理模型。Water supply networks are important components of lifeline engineering. Based on the series of study achievements of our research group,this paper begins from the seismic response estimation of buried pipe networks,and further modifies the leakage model,and then finishes the real-time dynamic function analysis of buried water supply networks with leakage characteristics combined with the theory of transient flow. At last,a physical function analysis model is built and can be applied to the function analysis of buried water supply networks during earthquakes.
