The article is devoted to the analysis of static and dynamic calculation of the interface of an approach embankment to artificial structures, such as a railway bridge and culverts? the main indicator of the stable operation of an approach embankment to an artificial structure is the stiffness of the base. Calculations are performed in the Midas software package, taking into account the interface of the transition sections from the unfixed roadbed to its fortified part with bored piles and the bridge abutment. A static loading scheme with a C14 time load and a dynamic loading scheme for an approach embankment with a time load from a high-speed train (South Korean KTX20 cars standard norms – 17,335 tons per wheel, 34,67 tons per axle) are considered, and the results are analyzed and compared. The analysis of calculation results is made. The boundary conditions are taken as "Springs on the base surface" – "Ground Surface spring". This function allows you to automatically create elastic or viscous boundary elements that are necessary for performing dynamic calculations. When selecting a grid, boundary conditions are automatically created on the left/right border of the selected grid, and an elastic constant is automatically calculated based on the material properties assigned to the elements. Based on the research, recommendations were made for the development of a detailed model, taking into account the dynamic impact of rolling stock on an artificial structure.
