Small vibrations of the pipeline model during the capital repairs are considered. Frequencies of the damping vibrations are determined with account for the influence of the internal friction in pipes' metal as well as the external resistance in underground pipeline sections. The dependence of frequency values on the lengths of underground sections and the soil rigidity is analyzed.
