Centrifuge modelling of pile pull-out tests in expansive soil (2019)
Conference Proceeding
Smit, G., Jacobsz, S., Gaspar, T., & Osman, A. (2019). Centrifuge modelling of pile pull-out tests in expansive soil. In Proceedings of the 17th European Conference on Soil Mechanics and Geotechnical Engineering (ECSMGE) (1-18). https://doi.org/10.32075/17ecsmge-2019-0175

Designing foundations of wind turbines in expansive soils present a challenge. Piled foundations are often used to mitigate some of the problems associated with construction on expansive soils. Swelling clays frequently occur in an unsaturated state... Read More about Centrifuge modelling of pile pull-out tests in expansive soil.

Numerical analysis of cavity propagation in deep trapdoor experiments (2019)
Conference Proceeding
Osman, A., Jacobsz, S., & Purchase, C. (2019). Numerical analysis of cavity propagation in deep trapdoor experiments. In roceedings of the 17th European Conference on Soil Mechanics and Geotechnical Engineering (ECSMGE) (1-7). https://doi.org/10.32075/17ecsmge-2019-0408

Large areas of the economically important Gauteng Province of South Africa are underlain by extensively weathered dolomite bedrock in which sinkholes are a common occurrence. Deep trapdoor experi-ments were conducted in the geotechnical centrifuge to... Read More about Numerical analysis of cavity propagation in deep trapdoor experiments.

Preparations for field testing for the performance validation of piled wind turbine foundations in expansive clays (2019)
Conference Proceeding
da Silva, T., Haigh, S., Elshafie, M., Jacobsz, S., Day, P., & Osman, A. (2019). Preparations for field testing for the performance validation of piled wind turbine foundations in expansive clays. In D. Kalumba (Ed.), Proceedings of the 17th African Regional Conference on Soil Mechanics and Geotechnical Engineering (661-666)

Field-testing of piles in an expansive clay is required for the validation of the design criteria for wind turbine foundations in such soil profiles. The test programme includes lateral load tests to investigate the horizontal stiffness of the soil a...

An expansive clay for centrifuge modelling (2019)
Conference Proceeding
Gaspar, T., Jacobsz, S., Smit, G., & Osman, A. (2019). An expansive clay for centrifuge modelling. In Proceedings of the 17th European Conference on Soil Mechanics and Geotechnical Engineering (ECSMGE) (1-8). https://doi.org/10.32075/17ecsmge-2019-0421

This paper explores the development of an expansive soil which can be repeatedly reproduced for use in centrifuge models to investigate soil-structure interaction problems involving expansive soils. The study considered two materials, namely a sand-b... Read More about An expansive clay for centrifuge modelling.
