地震火灾（FFE）是一种常见的次生灾害，会给人类造成巨大损失。人们提出了大量的抗震回弹评估方法，但很少考虑FFE的影响。在本研究中，开发了一个基于多场景模拟的模型，用于评估在地震损坏和 FFE 的影响下，供水管网 (WDN) 在供应消防流量和原始需求方面的灾后性能。生成假设地震，并通过泊松分布模型和威布尔分布模型模拟FFE的时空分布。灾后性能通过两种类型的地震可靠性指标进行评估。开发的模型已应用于目前在中国运营的 WDN，该网络具有八种预先确定的地震场景。结果显示，消防流量集中在震后最初几个小时内。因此，在最初的几个小时内，原始需求和消防流量的可用性均受到显着影响，而在集中消防流量交付后，影响很小。所提出的模型量化了 WDN 在特定地震损伤和潜在 FFE 下的性能，可用于 WDN 的规划、设计和维护。
Fire following earthquake (FFE) is a common secondary disaster that can inflict great damage to humans. A large number of seismic resilience evaluation methods have been proposed, but few of them consider the influence of FFE. In this study, a multi-scenario simulation based model was developed to evaluate the post-disaster performance of water distribution networks (WDNs) in supplying both firefighting flow and original demand under the effect of seismic damage and FFEs. Hypothetical earthquakes were generated and the spatial–temporal distribution of FFEs was simulated by the Poisson distribution model and the Weibull distribution model. The post-disaster performance was evaluated by two types of seismic reliability metrics. The developed model was applied to a WDN currently operating in China with eight pre-determined earthquake scenarios. The results showed that the firefighting flow was concentrated in the first few hours after the earthquake. Thus, the serviceability of both original demand and firefighting flow was influenced significantly within the first few hours, while little impact was observed after the concentrated firefighting flow was delivered. The proposed model quantified the WDN’s performance under specific seismic damage and potential FFEs, and can be used for the planning, design, and maintenance of WDNs.
