Earthquake Damage Evaluation of Water and Sewage Lifelines -17 October 1989 San Francisco Earthquake

这是一个SGER项目，收集和研究1989年10月17日洛马普里塔地震的易损地震和结构反应/损坏数据。在1989年10月17日的地震中，旧金山地区的生命线系统、天然气管道、污水管道、电力传输和电力系统等遭受了相当大的破坏和服务中断。因此，它为评估这些为城市和社区服务的重要系统的安全性和服务运行提供了极好的机会。这个项目是收集和评估这次地震或水和污水设施的耐久性和损坏所产生的数据。要执行的任务包括：(1)一般损坏级别的损坏清单，(2)所有系统设施的清单并确定这些设施的地震设计标准，(3)确定当地岩土数据，(4)库存系统耐久性和损坏，以及(5)开发设施组件的损失算法并确定成功的设计解决方案。该项目将建立一个全面的数据库，并对地震安全、损失、供水和污水生命线系统的服务恢复和维修等复杂问题提供深入的见解。

This is a SGER project to collect and to study the perishable earthquake and structural response/damage data due to the October 17, 1989 Loma Prieta earthquake. The lifeline systems gaslines, sewer lines electric transmission and power systems etc. in the San Francisco area sustained considerable damage and service disruption during the October 17, 1989 earthquake. As a result it provides excellent opportunity to assess the safety and service operation of such vital systems, which service the city and community. this project is to collect and evaluate data resulting from this particular earthquake or endurance and damage of water and sewage facilities. The tasks to be conducted include: (1) damage inventory for general damage level, (2) inventory of all system facilities and identify earthquake design criteria for those facilities, (3) identify local geotechnical data, (4) inventory systems endurance and damage, and (5) develop loss algorithms for facility components and identify successful design solutions. The project will establish a comprehensive data base and provide in-depth insight into complex issues on the seismic safety, loss, service restoration and repair of the water and sewage lifeline systems.
