Influence of impact forces on the strength characteristics of the railway roadbed by O. G. Krasnov, N. N. Astanin

“…Increasing the humidity of clayey soils under impact loads is an important factor in reducing the values of ultimate stresses:- for clays with an increase in the yield index to 0.5 at an amplitude of vibrations of 300 μm, the ultimate stresses are reduced by 1.1 ... 1.28 times, with an increase in the yield index to 0.75 in 1.5 ... 1.96 times;- for loams with an increase in the yield index to 0.5 in 1.16 ... 1.21 times, with an in-crease in the yield coefficient to 0.75 in 1.58 ... 1.6 times.Operation of the rolling stock with oversized defects on the rolling surface of the wheels can lead to micro-shifts in the ground space, the accumulation of deformations and defects in the roadbed.…”
