PhD Studentship in thermal integrity testing of deep foundations ¿ instrumentation and interpretation


A fully funded 4-year PhD studentship funded through a CASE award sponsored by the Engineering and Physical Sciences Research Council and Arup is available in the Department of Engineering at the University of Cambridge under the supervision of Drs Mohammed Elshafie and Cedric Kechavarzi. The studentship has a start date of October 2017. Due to funding restrictions the studentship/project is only available to UK (full fees and maintenance) or EU citizens (fees only). We are unable to consider applications from any non-EU citizen for this studentship.

In the UK, the current industry standard to test the integrity of deep concrete foundations is to use Crosshole Sonic Logging (CSL). Although well established, this method has a number of known technical limitations as well as adverse construction safety aspect during reinforcement cage assembly. These issues are key factors in the foundation industry's wish to change to a better integrity testing method. This exciting research will build on from recent distributed fibre optic research at Cambridge University, investigating in a new area of thermal heat transfer to develop and prove an interpretation method to assess the structural integrity of deep foundations using distributed fibre optic sensors installed within foundations. The interpretation method will use the thermal data measured during the hydration of the curing concrete to determine the geometry of the as-built foundations. This research will run in parallel with two other PhD studentships into concrete and foundation support fluid at Cambridge University to collectively bring improvements to foundation construction in the industry.

As the research offers significant benefits to industry, the successful applicant will work closely with Arup and other industry partners. The student will carry out practical laboratory and field testing as well as advanced numerical simulations. The numerical work will focus on heat transfer modelling in piles and soil during concrete curing to study the influence of various parameters on concrete temperature in situ. This modelling will be validated against field data in order to develop guidance for the interpretation of thermal testing data and the assessment of foundation integrity. The research is conducted in partnership with engineering consultants Arup (http:///www.arup.com) Additional information on the academic supervisor is found at: http://www.construction.cam.ac.uk/centre-staff/mohammed-elshafie
