The article presents a solution of the problem of free bending oscillations of thin-walled gas pipelines of large diameter at semi-underground laying. The gas pipeline is considered as a cylindrical shell, which is affected by a stationary internal working pressure, longitudinal compressive force, and a distributed inhomogeneous load caused by soil pressure on the outer surface of the pipe. Comparison analysis is made of the frequencies of free oscillations of the gas pipeline at semi-underground and surface laying, in dependence of the values of geometric and mechanical parameters.
