FUNDAMENTALS OF CALCULATION OF STRESS STATE OF A SUBGRADE
Abstract
In some experts’ opinion evaluation of stress fields within under rail subgrade is accomplished with the help of formulae of mostly empiric character. This approach limits possibilities of exploring the processes of pressure wave propagation and of their interaction with soils at the moment of freight train motion along the rails. The article suggests a theoretical description of the studied dependencies and equations for numerical solution of the problems related to the processes within the stress fields of rail subgrade.
