The article presents the results of study of free oscillations spectrum of thin elastic shells. The natural frequencies of oscillations corresponding to the forms of free oscillations, for underground straight sections of gas pipelines are discussed. When calculating the changes in these frequencies, the coefficient of elastic resistance of the soil is taken into account, as well as added soil mass, the longitudinal force parameter, thin-wall parameter (ratio of pipeline wall thickness to its radius), the value of the internal pressure.
