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

这是一个SGER项目，旨在收集和研究1989年10月17日洛马普列塔地震引起的易逝地震和结构响应/损坏数据。在1989年10月17日的地震中，弗朗西斯科地区的生命线系统，天然气管道，下水道管道，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，它提供了评估为城市和社区服务的这些重要系统的安全和服务操作的绝佳机会。该项目旨在收集和评估此次地震或供水和污水设施的耐久性和损坏情况的数据。要执行的任务包括：（1）一般损坏程度的损坏清单，（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）确定当地的岩土工程数据，（4）库存系统的耐久性和损坏，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，深入了解地震安全、损失、服务恢复和供水和污水生命线系统的修复等复杂问题。

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.
