Abstract

An exact analytic solution to the problem of joint nonstationary oscillations of a semi-infinite underground pipeline and elastic soil caused by the propagation of a longitudinal seismic wave along its axis is obtained in the case when the pipeline end is clamped. The emerging stress-strain state for subsonic and supersonic modes of seismic wave propagation is studied. The results of this study can be used to calculate the deformation of oil and gas pipelines under seismic loads.

地震波作用下半无限地下管道的振动

摘要

在管道端部被夹紧的情况下，得到了纵向地震波沿其轴线传播引起的半无限地下管道与弹性土体联合非平稳振动问题的精确解析解。研究了地震波传播的亚音速和超音速模式的新兴应力-应变状态。研究结果可用于计算地震荷载作用下油气管道的变形。
