The distribution of the amplitudes oscillations in the body of rail subgrade of dune sands and outside of him

In the article the questions of oscillations propagation in the body of subgrade from dune sands and beyond are considered, arising during the train movement. The regularities of changing the amplitude oscillations are given depending on train speed, depth, location and distance of the considered point from the axis of the path. The formula has proposed for the analytical calculation of the oscillations amplitude at any point of cross section on subgrade from dune sands.
