The section of Geo-Engineering at Delft University of Technology (The Netherlands) is searching for a doctoral student to enhance the understanding and the modelling of the coupled hydro-mechanical behaviour of soft soils subjected to cycles of environmental and mechanical loads.

Soft highly organic soils are widespread in the foundation layers of the built environment all over the world. They contain organic matter, roots and fibres, which improve their mechanical response. However, these soils are extremely vulnerable to climate-related hazards. Increasing climatic stresses, such as heat waves, drought, and more frequent intense precipitation accelerate the degradation of organic soils, by increasing their drying and shrinkage rate above the water table and their decomposition rate under water, with gas generation and exsolution. Both these mechanisms, drying and gas exsolution, ultimately contribute to significant land subsidence and reduction in available resistance. Quantifying the geotechnical engineering consequences of seasonally varying loads, including drying-wetting, temperature cycles and degradation, on organic soils is extremely challenging due to the complexity of a proper description of multi-physics gas-liquid-solid interaction. The project aims at deepening the understanding and the modelling of these coupled processes, to mitigate the climate-related hazard in natural soils and to assist in the design of durable innovative green solutions.

The twofold aim of the PhD project is:

• To experimentally investigate the coupled hydro-mechanical behaviour of organic soils subjected to cycles of environmental (e.g. drying and wetting, temperature) and mechanical loads. Soft soils reinforced with natural and artificial organic fibres will be tested, to quantify the role played by fibres, gas and fabric on their mechanical behaviour.
• To enhance existing constitutive models in order to include the effects of environmental factors such as drying-wetting cycles, temperature cycles and degradation in the prediction of their geotechnical properties.

The Nottingham Centre for Geomechanics (NCG) is currently undertaking two large multi-disciplinary projects related to investigating the behaviour of coal-mining spoil materials with a focus on the geotechnical, sustainability, environmental, socio-economic and long-term management challenges. NCG brings together expertise from the worlds of civil, geotechnical, and mining engineering as well as mathematics and material sciences to solve all forms of soil and rock-related design and construction problems. The projects are funded by the European Commission Research Fund for Coal and Steel (RFCS) and include project partners from across Europe. We seek a highly motivated researcher to join our team to work on this challenging project.

We are looking to recruit a post-doctoral researcher who will support the work of these RFCS projects as well as support the wider work of the research group. We are looking for someone with a strong numerical and/or constitutive modelling background in geomechanics, preferably someone with experience using ABAQUS.

Candidates should be inquisitive, with a strong interest in applied research, and the personality and drive to interact effectively with industry and project partners. They will have a first degree in Civil Engineering or cognate subject and will have been awarded a PhD (or have submitted their thesis for examination), ideally in an area of Geotechnical Engineering. The successful candidate will have good presentation and report writing skills. A good publication record will be an advantage but its absence should not hinder applications from those who have recently submitted their theses.

We are now seeking highly motivated PhD students to conduct advanced research topics associated with geoenergy, geoenvironment and geohazards in Westlake University (a brandnew high-level research institution in China).
Dr. Sergio’s M3 Lab has the expertise, and in-house codes, on several areas of computational, physical and theoretical modelling of complex processes commonly found in Civil, Environmental and Mining Engineering.

Research Topic

The PhD program mainly focuses on interactions between solid, liquid and gas phases at microscopic scale during the processs of gas transport in saturated granular materials. Both experimental and numerical studies will be conducted to understand the complex multiphysical process. The Lab provides advanced experimental facility and in-house code (MECHSYS: http://mechsys.nongnu.org/) to perform the research. The outcome of the research is expected to be beneficial to the gas hydrate development, carbon dioxide sequestration and solid waste disposal, etc.

How to apply

Please contact Professor Sergio Torres (s.torres@westlake.edu.cn) with your CV and transcripts.
