| Popis: | The paper presents a research regarding the stresses in the railway embankments taking into account the static and dynamic action of the rolling material. The railway is subjected to heavy and complex stresses, and the axle loads increase with the traffic speed. Therefore, it is necessary to know as accurately as possible the service conditions for the embankments to help the railway infrastructure to provide a sure and continuous support for the superstructure. To search an earth bulk, it is necessary to know the distribution of the tensions inside it. The design model admits the idea of a homogeneous, isotropic, continuous and linear space that can be deformed. The study presents the manner in which railway vehicle loads are transmitted from the rail to the sleeper and then to the embankment through the ballast bed. The simulation was made with the Slope software, and maximum deformations for various heights of the embankments loaded with railway convoys were produced. |
