Assessment of Lifeline Response and Recovery Performance Using Data from the 1987 Whittier Narrows Earthquake

惠蒂埃·纳罗斯地震为评估1971年圣费尔南多地震对地震设计和生命线性能的影响提供了一个机会。圣费尔南多地震是这些系统抗震设计的一个重大转折点，洛杉矶有机会从这一领域进行的研究中受益。因此，收集惠蒂尔纳罗斯地震的反应和恢复数据不仅可以保存重要但易腐烂的数据，还可以评估研究应用和有效性。这项拟议研究的目标是：(1)收集、回顾和记录1987年10月1日惠蒂尔窄带地震的生命线系统性能(即响应和恢复)数据；(2)利用惠蒂尔窄带地震和1971年圣费尔南多地震的数据，为不同的生命线系统开发初步的响应和恢复模型；以及(3)评估1971年圣费尔南多地震后在生命线地区开展的研究对改进地震设计以及生命线应急反应和准备程序的影响。将执行的具体任务包括：(1)数据收集和审查；(2)与生命线工作人员面谈；(3)制定初步反应和恢复模式；(4)比较1971年圣费尔南多地震和1987年惠蒂尔纳罗斯地震期间生命线反应和恢复情况；以及(5)评估1971年圣费尔南多地震后开展的研究对生命线抗震设计和性能的影响。

The Whittier Narrows earthquake offers an opportunity to assess the impact that research conducted as a result of the 1971 San Fernando earthquake has had on the earthquake design and performance of lifelines. The San Fernando earthquake was a major turning point in the seismic design of these systems, and Los Angeles has had the opportunity to benefit from research conducted in this area. Therefore, collecting response and recovery data from the Whittier Narrows earthquake would not only allow the preservation of important but perishable data, but also an assessment of research application and effectiveness. The objectives of this proposed study are to (1) collect, review, and document lifeline system performance (i.e., response and recovery) data from the October 1, 1987 Whittier Narrows earthquake; (2) develop preliminary response and recovery models for different lifeline systems using data from the Whittier Narrows earthquake and the 1971 San Fernando earthquake; and (3) assess the impact that research in the lifelines area conducted after the 1971 San Fernando earthquake has had on the improvement of seismic design and emergency response and preparedness procedures for lifelines. Specific tasks that will be performed include (1) data collection and review; (2) interviews with lifeline personnel; (3) development of preliminary response and recovery models; (4) comparison of lifeline response and recovery performance during 1971 San Fernando earthquake and 1987 Whittier Narrows earthquake; and (5) assessment of impact of research conducted after 1971 San Fernando earthquake on seismic design and performance of lifelines.
