Abstract. The article reviews the propagation of elastic waves in soils during rotational movement of underground pipeline. One-dimensional cylindrical shear waves are discussed and solution methods are developed that allows the application arbitrary loads on the boundary. Based on the publication the numerical calculation program was compiled. The calculation results displayed that when underground pipeline moves single direction, the stress increase, a reverse pattern was obtained, the stress decreases. Attenuation of waves with distance is due to the fact that deformation energy is dissipated into an expanding cylindrical layer of soil

Keywords: soil, underground pipeline, cylindrical wave, sections, wave parameters
