摘　　要：为了分析地震波作用下埋地管道的位移反应,以震时埋地管道的接头损坏作为主要破坏模式,采用波动理论计算管道的轴向变形,讨论了地震波入射角、剪切波速、管径等参数对管道变形的影响,并比较了两种管土间轴向变形传递系数的计算差异,建议采用《室外给水排水和燃气热力工程抗震设计规范》(GB500 32-2003)中给出的变形传递系数进行埋地管道抗震验算。Based on the failure mode of the conduit joints under seismic wave propagation, seismic performance analysis of the buried pipeline is performed with wave theory method by mainly considering the conduit＇ s axial deformation. And factors which influenced the pipeline＇ s axial deformation such as seismic wave＇ s incident angle, shear wave velocity, pipe＇ s diameter and wall thickness are deeply discussed in this paper. Finally, two different methods for calculating axial deformation transfer coefficient are compared, and the formula in ＇ Code for seismic design of outdoor water supply, sewerage, gas and heating engineering GB 50032-2003 ＇ is suggested to check buried pipeline＇ s seismic deformation.
