Deformation model of a ballast prism, stabilized by geosynthetics, under heavy axial load
The purpose of the study is to develop a mathematical model describing the deformation process of crushed stone ballast stabilized by geosynthetics. To achieve this goal, an elastic-viscoplastic soil model with a layers of geosynthetics has been adapted and certified. As a result of numerical modeling using FEM, the main mechanism for reducing the magnitude of plastic deformations of railway ballast during its stabilization by geosynthetic materials has been revealed. The aim of the work is to develop a methodology that makes it possible to reasonably assign measures to increase the load-bearing capacity and reduce the deformability of the substructure railway track.
