摘　　要：埋地管道在土体中,四周被土体包围。地震时,由于管道与沙土等介质的相互作用而引起管道运动,在管道中产生地震应力。本文针对地震波作用下埋地管道的运动特点,建立土壤和埋地管道的相互作用模型。应用ANSYS有限元软件对埋地管道进行模拟试验,得出在地震作用下,埋地管道的位移随地震波的响应情况。同时,提出了埋地管道的简化力学法,为今后的研究提供帮助。Buried pipelines are surrounded by soil.The seismic stress in pipelines is caused by the interaction between pipelines and soil while earthquake.For the characteristics of the movement of the buried pipeline,the text establish the interaction model of buried pipeline.Futhermore,application of ANSYS finite element software for buried pipeline simulation experiments,we obtain the dynamic response situation of buried pipelines under the seismic waves.Meanwhile,the mechanical method of buried pipeline was proposed to help others.
