Calculation of inherently deformable pipelines lying on a solid viscoelastic base with random characteristics

In this paper, the problem of the strength of underground pipelines is considered under the following assumptions: a) the pipeline is treated as an infinitely long viscoelastic rod located on a solid viscoelastic base of the Winkler type; b) the load from the overlying soil and the coefficient of resistance of the soil are assumed to be random functions of the coordinate and time; c) the heterogeneity of the soil is considered small enough to allow the expansion of the pipeline deflections in a row by a small parameter.
