摘要 提出了一种新的地震可靠性评估模型，该模型量化了地震对供水管网水力行为的影响。在目标区域产生概率性地震事件，通过地震可靠度指标评价地震破坏深度。开发的模型应用于多个案例研究，并用于深入研究供水系统如何对地震事件进行水力响应，以及哪些系统特征会影响地震时系统的性能。首先，对韩国真实网络在遭受不同震级和不同地点的地震时的系统可靠性进行了量化。接下来，评估完整和简化网络模型的可靠性，以研究系统布局如何影响可靠性评估。最后，比较了不同配置、管道尺寸和系统密度的管网的地震可靠性和各种地震损伤指标。
AbstractA new seismic reliability evaluation model is proposed that quantifies the impact of earthquakes on hydraulic behavior of water supply networks. Probabilistic seismic events are produced in the target areas, and the depth of earthquake failure is evaluated by seismic reliability indicators. The developed model was applied to several case studies and used for an intensive examination on how a water supply system hydraulically responds to a seismic event and what system characteristics influence the system’s performance in the event of an earthquake. First, the system reliability of a real network in South Korea when subjected to earthquakes of various magnitudes and locations was quantified. Next, the reliabilities of full and simplified network models were evaluated to investigate how system layouts affect the reliability evaluation. Finally, networks with different configurations, pipe sizes, and system densities were compared with respect to the seismic reliability and various seismic damage ind...
