AbstractThe method for determining the internal forces in longitudinal sections of the pipe wall based on the numerical analysis method has been proposed. The two-dimensional finite-element model simulating the annular section of the pipe and surrounding soil body are used. The external loads are presented as vertical pressures applied at the level of the pipe top +0.5 m. The calculation is performed by the iterative method with the account of the deformation parameters of the elements. The computation results conform well with the experimental data.
