In order to improve the transport infrastructure of the Republic of Uzbekistan, monolithic structures of bridges and overpasses began to be used. The article presents the calculation of a monolithic bridge on the 1083rd km of the M-39 highway passing through the city of Samarkand. The main goal was to determine the structural parameters of the overpass with seismic load, especially the influence of friction forces on the overpass foundation. The calculations were carried out using the Midas Civil software package using the finite element method (FEM) based on linear spectral theory. In the calculations of the Midas Civil PC, carried out within the framework of linear spectral theory, it was determined that the pile pressure on the lower soil does not exceed the limit and the maximum value of the bending moment coincides with the pile head moment.
