摘　　要：埋地管道地震作用下的破坏因素源于地震引起的永久地面变形(PGD),其中管道-土体间相互作用决定土体位移作用到管体的大小。利用离心机试验技术模拟埋地管道在逆断层大位移下的反应特性,重点讨论断层与管道的交角、断层位移大小、管土相互作用、管径和埋深五个参数对管道破坏的影响水平。实验结果表明:上述参数对管道断层作用的反应均有明显影响,其中断层的位移量、管土相互作用、埋深和管径的影响更为显著。本文的研究结果对于管道经过断层区的抗震设计有十分重要的意义。Buried pipeline systems are usually referred to as lifeline systems due to their support of human daily life and economic development,energy-transportation and water-transmission.The primary hazard for buried pipelines during earthquake events is permanent ground deformation（PGD）.However,an important factor to control the response of the buried pipeline to PGD is the interaction between the soil and the pipeline.In this study,a centrifuge model test was conducted to investigate the effect of PGD on a pipeline.The normal pressure of the interface between pipeline and soil was measured using the smart tactile pressure sensor system,and other important parameters such as PGD,strain rate,pipeline diameter,the orientation of the pipeline and soil types were also tested to determine the influence on soil-pipeline interactions.All of the PGD,pipeline-PGD orientations,pipeline diameters,and soil types were key factors affecting the interaction between soil and pipeline.The results of this research could be used in the aseismic design of pipelines passing through the PGD.
