埋地管道在地震波作用下的动力响应分析
|
摘要
埋地管道是一种特殊的地下结构.地震时由于管道与沙土等介质的相互作用引起管道运动,在管道中产生地震应力.针对地震波作用下埋地管道的运动特点,应用有限元分析方法对埋地管道进行模拟试验,结果表明水平地震沿x方向和y方向共同激励作用下管道的横向位移响应远远小于轴向位移响应.
Buried pipeline is a particular kind of underground structure.The pipelines is to be caused into motion by the interaction between the pipelines and soil when earthquake takes place,resulting seismic stress in them.According to the motion characteristics of the buried pipelines under the action of seismic waves,the simulation experiment was carried out with finite element analysis method.Its result showed that axial displacement response was greatly larger than that of transverse displacement under the combined action of horizontal seismic excitation in both x-and y-directions.
