Behavior of Large Diameter Water Pipe at Seismic Faultby M.J. O'Rourke and R. DobryABSTRACTThe proposed work is a collaborative research project on the seismic behavior of potable water systems with particular emphasis on buried pipe. The project has two specific goals. The first is to fully and properly document the behavior of buried pipeline and other water system components in the affected areas of Turkey and Taiwan during the earthquakes in 1999. The second goal is to investigate the behavior of large diameter water pipe subject to the fault rupture hazard. In terms of the first goal, the data gathering and subsequent analysis will be directed at establishing fragility relations based upon key engineering parameters and mechanics, as opposed to simply a statistical analysis of empirical observations.The earthquakes in Turkey and Taiwan provide a unique opportunity to develop a fundamental understanding of the behavior of large diameter pipe subject to the fault rupture hazard. In both events, large diameter water pipe were severely damaged where they transversed the surface expression of a fault The opportunity is unique in the sense that surface faulting has not intersected large diameter pipe in past events. We plan to develop a fundamental understanding of this hazard by comparing the results of computer simulation and small scale laboratory modeling using the Rensselaer Geotechnical Centrifuge `with observed full scale behavior.

M.J. O'Rourke和R. dobryy[摘要]提出的工作是一项关于饮用水系统地震行为的合作研究项目，重点是埋地管道。该项目有两个具体目标。第一个是全面、恰当地记录1999年地震期间土耳其和台湾受影响地区的地下管道和其他水系统组件的行为。第二个目标是研究大直径水管在断层破裂危险作用下的行为。就第一个目标而言，数据收集和随后的分析将针对建立基于关键工程参数和力学的脆弱性关系，而不是简单地对经验观察进行统计分析。土耳其和台湾的地震提供了一个独特的机会来发展对断层破裂危险下大直径管道行为的基本理解。在这两起事件中，大直径水管在它们横贯断层地表的地方遭到严重破坏。在过去的事件中，地表断层没有与大直径水管相交，这是一个独特的机会。我们计划通过比较计算机模拟和使用伦斯勒土工离心机的小型实验室模型的结果与观察到的全尺寸行为，对这种危害有一个基本的了解。
