In general, the overall effects of seismically induced damage to lifeline systems continues for several months following the earthquake. A methodology to assess such damages to lifeline systems is currently not available. A data base is not available at the present time to verify the analysis of time-dependent post-earthquake damage to buried pipeline systems. This study provides a method to assess the post-earthquake damage to buried pipeline systems. This research will develop an objective measure of earthquake damage to underground pipeline systems based on field data from the 1983 Coalinga earthquake and the 1979 Imperial Valley earthquake.

总体而言，地震对生命线系统造成的破坏的总体影响在地震后持续了几个月。目前还没有评估这种对生命线系统的损害的方法。目前还没有数据库可用来验证对埋地管道系统震后破坏的时间相关分析。本研究为评估埋地管道系统的震后破坏提供了一种方法。这项研究将根据1983年科林加地震和1979年帝国谷地震的现场数据，制定地震对地下管道系统破坏的客观衡量标准。
