Abstract
To assess the strength and deformability of the railway road bed must have analytical expressions for calculating the oscillation amplitudes at any point in the road bed and beyond. The results of experimental determination of the amplitudes of the oscillations in the sub grade of sandy loess sin the Republic of Uzbekistan. Shows plots of the decay amplitudes of the oscillations in the sub grade and beyond by passing high-speed trains. The analytical dependence of the calculation of the amplitudes of the oscillations.
Keywords: Embankment, roadbed, the amplitude oscillation damping, vibrodinamika, loess-like sandy loam
