本文对埋在弹性介质中的连续长管道的动力特性进行了长波长低频分析。使用壳模型的管道，它示出的动态放大的轴向和环向应力在管道中引起的由于行波平面波（纵向和剪切）取决于至关重要的周围土壤和管道的刚度的比率。结果显示的入射波的传播方向上的诱导应力的依赖性，泊松比和刚度的地面和管道材料。
A long wavelength and low-frequency analysis is presented here for the dynamic behavior of a long continuous pipeline embedded in an elastic medium. Using a shell model for the pipe, it is shown that the dynamic amplification of axial and hoop stresses induced in the pipe due to traveling plane waves (longitudinal and shear) depends crucially on the ratio of the rigidities of the surrounding soil and the pipe. Results are presented showing the dependence of the induced stresses on the direction of propagation of the incident waves, the Poisson's ratios and rigidities of the ground and pipe materials.
