Models & Apps

Software Applications : A complete and modular DSS (Decision Support System) to predict and optimize Maintenance & Renewal strategies for the Railway Track System. The first version of this tool was adapted to be used with data from REFER, E.P.E. Details on the application can be assessed here:

MODURAIL-LD: Computational tool to specifically assess the evolution of local track geometry defects. This application began to be developed within the project and will be further enhanced in order to be adapted and integrated within the MODURAIL DSS Application in the future.

The developed finite element (FE) model of the railway track performs a fully coupled thermo-hydro-mechanical (THM) analysis of the railway track. In addition to the mechanical behaviour of the different railway track components, the incorporation of constitutive models, suitable to describe unsaturated soils, allows to compute the deformational response not only to cyclic traffic loading, but also against environmental and hydro-geological actions. The THM FE model also simulates the runoff of rainwater enabling performance analysis of the different elements of the drainage system.
