PhD Position Train-Track-Embankment-Subsoil Interaction: Modelling, Validation and Application

Published Deadline Location
31 Oct tomorrow Delft

Job description

Within the research program RESET– “Reliable Embankments for the Safe Expansion of Rail Traffic” – ProRail, Deltares and TU Delft will work together to investigate the behaviour of moving trains on rail embankments with special attention to increasing train frequency and trainloads, and effects of climate change. TU Delft is recruiting 8 PhD students and 2 postdocs to work in this research program. One PhD position is available to work on train-track-embankment-subsoil interaction: modelling, validation and application.

Background:

The train, track, embankment and subsoil work together as a system. The static and dynamic behaviour of each component in the system and their interactions determine the performance of the whole system. Numerical modelling is the most economical and efficient method to understand the response and interactions in this system, to predict the embankment stability and its evolution over time due to changing loads including climatic stresses. The modelling and its validation are closely related to the laboratory and field tests, the development of material constitutive models, the development of new measurement and monitoring methods and the risk assessment.

Project description

The project will be conducted in close collaboration with the other PhD and postdoc projects and with all partners in RESET. The PhD student will develop a 3D FE train-track-embankment-subsoil dynamic interaction model, which will enable (a) Modelling with sufficient accuracy the  mechanical behaviour of rail, rail-pad, sleeper, ballast, embankment and subsoil; (b) Determining the dynamic train loading on/in the embankment and subsoil to facilitate the development and use of soil constitutive models; (c) Predicting the embankment and subsoil behaviour under train loading to facilitate the assessment of stability risk as a function of axle load, speed, train frequency/length, at a certain location with certain hydraulic conditions; (d) Facilitating the determination of equivalent load for 2D static and dynamic LEM or FEM analyses; (e) Bridging laboratory tests and field tests for the development of new measurement and monitoring.
