2、ic 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 pro

3、vide 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 whi

4、ch 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. Keywords: railway emba

5、nkment stability; rail sleeper load; transmission of stresses in the railway; failure mode; bearing capacity; fill embankment. 1. Introduction The railway is subjected to dynamic loads originating in the weight of the moving rolling material, in the shocks in the joint area, irregularities and other

6、 causes related to deviations from admitted tolerances. These stresses are transmitted through the rail-sleeper system to the ballast bed towards the embankment, where stresses and strains due to these forces and the own earth height occur. 2. Railway embankments and surcharge loads 2.1. Generalities. Static and dynamic loads. Railway embankments are subjected to stresses coming from convoy traffic, own weight and other accidental stresses affected by the vibrations caused by railway traffic a
