Data Collection on Bay Bridge Damaged during October 17, 1989 Earthquake

这是国家地球物理研究所的一个项目，旨在收集和研究10月17日洛马·普里埃塔地震引起的易腐烂地震和结构反应/破坏数据。该项目正在进行的工作是收集和分析1989年10月17日地震造成的旧金山湾大桥的破坏数据。在上层甲板发生故障后立即开始的密集修复过程中，这些数据正在迅速消失。与加州交通部(加州交通部)合作，已恢复并继续收集关于严重损坏的桥梁构件(包括坍塌的桥面)的极其宝贵的数据。这些工程数据将被处理和分析。当局会拟备一份有关这类资料的报告，包括对大桥反应和设计考虑的影响。

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. Work underway in this project is to collect and analyze damage data of the San Francisco Bay Bridge due to the October 17, 1989 earthquake. Such data is rapidly disappearing during the intensive repairing process commenced immediately after the upper deck failure. In cooperation with the California Department of Transportation (Caltrans), extremely valuable data on severely damaged bridge elements including the collapsed deck has been recovered and continues to be collected. This body of engineering data will be processed and analyzed. A report of such information, including the implication to the bridge response and design consideration will be prepared.
