CALCULATION OF BALLAST BED STRESSES UNDER VERTICAL LOADS BY THE COEFFICIENT OF RIGIDITY

A method is described for calculating ballast bed stresses by the coefficient of rigidity, developing a system of linear equations on the condition of deformation that the sleeper deflection in any point must be equal to the sum of compression of the ballast bed and sinking of the subgrade. By this method the bottom pressure distribution below the sleeper can be calculated, and, from it, the ballast pressure distribution between bed and subgrade. The stress distributions below a timber cross tie and a concrete one are illustrated by an example.
