Abstract: The article presents the field measurement results of the stress states of roadbed thawed soil subgrade during the passage of trains. The dependences of the vertical and horizontal stresses on the velocity of the rolling stock motion, the axle load, and the distance from the sleeper sole have been obtained.

Key words: dynamic vibration impact, vertical and horizontal stresses, thawing subgrade, stress rise rate
