PhD Position Reliability/Risk-Based Modelling for Assessing Railway Embankment Stability
The current reliability framework for the stability assessment of railway embankments is derived from the general-purpose Eurocode standards that may be overly conservative in their implementation in the current guideline. This project will contribute to developing a new framework, by revisiting the approach to achieving target safety levels for railway embankments and the underlying assumptions from the Eurocode standards. It will include consideration of full and semi-probabilistic approaches, partial factors, characteristic values, target reliability levels, fragility curves, various data sources and real-time modelling, and builds on the advances made by TU Delft in assessing flood defence infrastructure through the NWO project Reliable Dykes.
This project aims to: (a) enhance the reliability/risk-based framework, which is tailored to the characteristics of loads and resistances in Dutch railway embankments, through advanced probabilistic modelling techniques; (b) account for the site characterisation of embankments and subsoil layers, including the statistical characterisation of geometric and geologic features, and the spatial variability of soil properties within soil layers; (c) perform 2D and 3D numerical modelling of embankment reliability, leading to the development of 3D stochastic (e.g. Random Finite Element Method) models for reliability-based assessments of embankment stability and allowing for material behaviours including creep and strain localization; (d) develop and validate numerical tools for application in engineering practice.
The project will be done in close collaboration with other projects within the research program RESET – “Reliable Embankments for the Safe Expansion of Rail Traffic” – a joint initiative between ProRail, Deltares and TU Delft.
We are looking for a candidate with an MSc degree in Geotechnical Engineering or a related field. The candidate should have a strong background in numerical modelling and soil mechanics, and have a genuine interest and aptitude for the development, computer implementation and application of numerical and probabilistic-based algorithms. The candidate should have excellent computer programming skills, proficiency in verbal and written English, and experience with team-work.
Doing a PhD at TU Delft requires English proficiency at a certain level to ensure that the candidate is able to communicate and interact well, participate in English-taught Doctoral Education courses, and write scientific articles and a final thesis.
