In collaboration with ARUP, the Department of Civil, Environmental and Geomatic Engineering of University College London has funding from the EPSRC for an EngD studentship (4 year programme) for the following project:

Finite Element Modelling of 3D Geotechnical Problems and Comparison with Simple Solutions

Arup have been at the forefront of the development of 3D Finite Element techniques in the field of Geotechnical Engineering. Arup and UCL have a suite of 2D and 3D finite element software packages to solve complex problems. There are a range of standard geotechnical problems where 3D effects matter. Simplified modelling solutions have previously been developed; however, the accuracy of these simplifications is uncertain. This research will identify some of these standard 3D problems and will test them using comprehensive 3D modelling. The range of geotechnical problems where 3D effects matter includes:-

• Tunnel/NATM construction sequences in soil and jointed rock mass
• Old cast iron tunnels with several segments connected by radial and longitudinal bolts
• Piled rafts and pile groups
• Basement walls including soldier pile walls, basement corners and berm excavation sequences
• Sheetpile designs including simplifying assumptions for wall friction and clutch slippage/oblique bending etc

Key research outcomes:

• Identify a suitable constitutive model for the selected 3D problem
• Examine and interrogate typical modelling assumptions used fro 3D problems
• Compare with outcome of detailed 3D models, theoretical and measured data
• Assess the conservatism and risks involved in the simplified solutions
• Develop new simplified techniques where risks on existing simplified solutions exist

Person Specification:

The ideal candidate is likely to have a degree (Masters) in soil mechanics or civil engineering with a strong background in finite element modelling. Practical experience is desirable but not essential. The candidate needs to be an innovator keen to:
• spend the necessary time in the design office;
• understand construction processes;
• understand the use of finite elements and become a competent practitioner and modeller;
• understand constitutive models and various 2D and 3D software packages used in the industry;
• develop new calculation rules or computational short-cuts

Applications:
Applications are invited from permanent UK residents with a degree (MSc in a related subject), and possibly some industrial experience.

For a place on the EngD programme funded through EPSRC awards, applicants must meet the EPSRC eligibility requirements. EngD Funding is available for applicants who have been working residents in the UK for at least three years prior to the proposed commencement of the programme.
