The problem of the impact of a longitudinal wave on a system consisting of successively located wells and pipelines of finite length, interacting with soil by elastic-viscous law is considered in the article. The ends of the pipeline are fixed to massive wells that have volume and mass. The size of the largest well is significantly less than the length of the pipeline, so the deformation of the well can be ignored, i.e. the well can be considered an absolutely solid body. We believe that for each section of the pipeline bounded by wells, the characteristics of the soil and pipeline differ. The problem is solved numerically using an explicit finite difference method. A longitudinal wave in soil acts as a traveling sine wave. The study provides a comparative analysis of the results for certain values of the elastic and viscous interaction coefficients and wave propagation velocity. The results of the study showed that the well has a significant impact on the stress state of the pipeline.
