Theoretical values of the interaction parameters of the underground pipeline with the soil

The assessment of the effect of the deformability of the underground pipeline on the linear coefficient of longitudinal shear under various boundary conditions at the ends of the pipeline is given. The example of stretching a finite one-dimensional elastic pipeline (bar) under the action of an axial force is considered. The solution of the problem of shear displacement of the pipeline located in a half-space is presented on the basis of the elastic body model. The results of theoretical calculations are compared with known experimental data.
