The use of stone columns as mitigation of earthquake-induced soil liquefaction

Soil liquefaction – the sudden strength loss of foundation soil caused by load transfer from soil grains to groundwater – is one of the biggest sources of financial loss caused by earthquakes. One possible solution, developed by Keller, is the stone column, a means of both stiffening the soil and increasing the potential drainage.

The proposed project is to carry out physical modelling of stone columns in liquefiable soil and assess the variables controlling their performance and their performance relative to alternative measures.

The successful applicant will be fully trained in the use of the geotechnical centrifuge and earthquake actuator at the University of Dundee. This project is in association with Keller, who will participate in the management of the project.

Candidates should hold or expect to gain a first class degree or a good 2.1 and/or an appropriate Master’s level qualification (or their equivalent).

The full award will cover fees at the Home/EU rate and will provide an annual stipend at standard EPSRC rate.
