A joint PhD position on the resilience of infrastructure earthworks subjected to extreme rainfall at Newcastle University and Durham University

Applications are welcome for a joint PhD position between Newcastle University and Durham University. The main objective of this doctoral project is to devise, via analytical and numerical modelling, practical solutions to enhance the resilience of infrastructure earthworks (such as dams, embankments) subjected to extreme rainfall events. The PhD candidate will work on the development of a constitutive model to predict the hydromechanical behaviour of unsaturated soils subjected to different types of stress paths (i.e. isotropic loading and unloading, wetting and drying, shearing). The model will then be implemented into a numerical Finite Element code to assess the stability of infrastructure earthworks and evaluate the effectiveness of several stabilisation measures (e.g. drainages, water runoff interceptors, etc.) with an unsaturated soil mechanics perspective. 

We are looking for a PhD candidate in geomechanics

Would you like to influence the success of our high profile project BIOGEOS and gain a sense of contribution in building the next generation of sustainable geotechnics? If so, this is what you will do by joining our highly motivated team at the the laboratory for Soil Mechanics (LMS) of the Swiss Federal Institute of Technology, Lausanne (EPFL).

BIOGEOS (BIO-mediated GEO-material Strengthening) is supported by an Advanced Grant of the European Research Council, awarded to Prof. Lyesse Laloui in 2018. We target the establishment of innovative, sustainable processes within mainstream geo-technical practices. Among the techniques developed at LMS is that of biocemented geo-materials. The significant impact of bio-cementation ranges from the protection of infrastructure
against liquefaction & poor quality of foundation soils to mitigating risks related to landslides and soil erosion which are intensified by extreme weather. BIOGEOS aims to crystallize new knowledge into constant innovation and implement state-of-the-art advances in the fields of micro-structural inspection, numerical modelling and material characterization.

Development of a novel rock anchoring system for floating renewable energy mooring

This project will develop understanding and design procedures for a novel rock anchor that has been developed for simple installation in offshore environments where high tidal current velocities and environmental controls exist. The anchor concept has the benefit of being self-drilling and does not require any additional grouting operations. The anchor will be designed and optimised to operate under the specific requirements for floating tidal stream generators and future floating wind. The research will use a mix of advanced numerical simulation and laboratory validation to develop simplified design and specification techniques.

• Application deadline: Tuesday, December 15, 2020
• Interviews: Early, 2021
• Start date: Before 31st March 2021
• Funding notes: European/UK Nationals. Only The 42 months studentship (3.5 years) will cover tuition fees and an annual stipend starting at £16,000 per year (approx. net income of £1330 per month).

PostDoc (f/m/x)- in Computational Geomechanics and Multiscale Modelling

Energy and environmental aspects of geoscience remain the greatest challenges that our society will face in the coming decades. To provide a numerical tool for environmental protection (e.g. sub-surface integrity) and energy transition (e.g. underground energy storage), Department of Environmental Informatics develops an open-source Finite Element platform, OpenGeoSys in C++. The tool enables us to simulate multi-physical processes in sub-surface such as fluid and heat transport, or rock deformation and failure. For simulation of discontinuous deformation or crack propagation in rock, a variational phase-field (VPF) model has been adapted and implemented in OpenGeoSys (OGS-6). Within the GeomInt2 project (www.ufz.de/geomint) the VPF method shall be further developed and applied to various applications such as field experiments in the Underground Research Laboratories and Mines in Mont Terri (Opalinus clay) and Springen (salt rock), respectively.
