Based on one industrial underground pipeline,with soil-pipe interaction and traveling wave effect taken into consideration,a finite element model was built to study the dynamic response of pipelines under uniform and non-uniform excitation,and the influence of some relative factors was analyzed.The results are:the peak value of the displacement response curve under non-uniform excitation,as well as shape,differs from that under uniform excitation.Horizontal displacement under non-uniform excitation is apparently greater than that under uniform excitation,while vertical displacement under non-uniform excitation is slightly greater than that under uniform excitation.The stress response of one monitor point differs from that of other points on the same section under both uniform and non-uniform excitation,and the stress response under non-uniform excitation is more intense compared to that under uniform excitation.Displacement and stress of a pipeline in the subsurface is usually influenced by the change in soil properties and pipe trend and bucking under seismic excitation.
