Early Post - Earthquake Damage Detection of Lifeline SystemsUsing Data Collected from the September 1985 Mexico Earthquakes

该项目的目标是制定一种方法，以便在震后早期检测生命线的破坏情况，并收集和利用1975年9月墨西哥地震的现场数据。墨西哥城的水利建设和运营总局（D.D.F.）记录了大量关于输水系统损坏以及水压梯度变化的数据。这些数据可用于帮助制定震后生命线的早期损伤检测方法。这种方法能够在不切断对未受损地区的重要供应的情况下保留剩余的储存供应，并加快和更有效地管理随后的反应和恢复工作。正在处理的四个主要任务是：(1)收集、审查和记录1985年墨西哥地震的水系统性能数据；(2)为关键水系统组件开发全面的地震脆弱性模型；(3)制定早期震后破坏检测方法；(4)在1985年9月墨西哥地震中演示该方法。重点是任务2和任务3。

The goal of this project is to formulate a methodology for early post-earthquake damage detection for lifelines and to collect and utilize field data from the September, 1975 Mexico earthquakes. Considerable data on water transmission system damage, as well as water pressure gradient changes, were recorded by the General Directorate of Hydraulic Construction and Operations (D.D.F.) in Mexico City. These data can be used to help formulate an early post-earthquake damage detection methodology for lifelines. This methodology has the capability to preserve surviving storage supplies without having to cut off vital supplies to undamaged areas, and expedite and more effectively manage ensuing response and recovery efforts. Four major tasks are being addressed: (1) Collect, review, and document water system performance data from the 1985 Mexico earthquakes, (2) Develop comprehensive earthquake vulnerability models for critical water system components, (3) Formulate an early post-earthquake damage detection methodology, and (4) Demonstrate this methodology for the September 1985 Mexico earthquakes. The major emphasis is on tasks 2 and 3.
