Abstract
EN: Abstract. Investigation of damages of the subgrade slope in combination with its overwetting and rolling
stock loading, which significantly affects safety traffic of the railway transport, has been carried out. The
complex method of slope stability estimation of the subgrade is developed, which includes calculation of
loads and vibration action of rolling stock on the main site of the subgrade, as well as the dynamic model
of vibrations propagation in the body of the subgrade embankment and the model of plastic deformations
accumulation. Dynamic and nonlinear plastic models are based on a finite-element model of the cross
section of the subgrade. The plastic model takes into account the characteristics of soil strength of the
subgrade, depending on the area of the vibration load impact. The developed method allows to carry out
the estimation of external and internal factors impact on occurrence of subgrade destruction, which is of
practical value for safety state estimation of the railway transport.
