Resumo
The previously proposed method of one-dimensional deformation of soil is used to solve the problems of joint seismic vibrations of an underground pipeline and elastic soil under nonideal contact conditions assuming that there is sliding at the interface and that resulting shear stresses at it are proportional either to the relative displacement of the soil particles and pipeline or to their relative speed of motion. The dependence of maximum stresses in the pipeline on the coefficients is investigated under boundary conditions. For supersonic flow around the pipeline, resonance is observed with decreasing shear stresses at the interface.
