CALCULATION OF STATIC STRESSED STATE OF THE "EARTH BED - WEAK BASE" SYSTEM
On the basis of the finite element method, there is investigated the static stressed state of the "earth bed - weak base" system under the influence of a constant train load with a view to practical evaluation of its stability. Multivariate numerical experiments made it possible to establish the regularities of stresses distribution in the earth bed body considering the elastic characteristics of the weak base.
