Résumé / Abstract
High Speed Rail (HSR) is growing and must innovate both in the direction of sustainable development and economically viable solutions. This article focuses on the reuse of materials in place using soil treatment. This technique is widely used in the road but is not well known in the railway. Numerical modeling of the infrastructure of HSR is presented. This modeling is performed in two stages, a first modeling is performed by the Finite Element Method (FEM) in order to determine the load distribution under the ties. This distribution is then utilized as input for semi-analytical calculations to determine the stress paths in the treated capping layer. These results will be used for the development of a fatigue test for specific railway features.
