中文摘要	燃气管网的局部破裂可能导致大片区域发生停气事故。为了模拟城市燃气管网破裂泄漏的故障传播范围及影响程度,进而为事故的预防工作提供科学的依据,该文综合研究了2种情况,即燃气管网节点破裂和管段破裂,把管段及节点计算流量子模型、燃气泄漏子模型以及管网压力分布计算子模型有机结合起来,建立了城市燃气管网的故障传播模型。并在此基础上进行了实际燃气管网的计算与分析。结果表明:该模型能够有效地预测燃气管网破裂泄漏的故障传播范围和影响程度。; A crack in a gas pipeline network can disrupt gas supplies to a large area.A failure propagation model for a city pipeline network was developed to simulate the scope of the failure propagation to provide a scientific basis for accident prevention.The model combined pipe-node flow model,gas leakage model,and pipeline network pressure distribution model was developed based on taking both node crack and pipe crack into consideration.Analyses of actual gas pipeline networks indicate that the model can successfully predict the scope of the failure propagation in a gas pipeline network.
