Centrifuge model testing for pile foundation reuse [PDF]

International Journal of Physical Modelling in Geotechnics, 2011
With continuous development in the urban environment, the ground is becoming increasingly congested with redundant foundations. The underground development of services and infrastructure already restricts the location of new building foundations and the redundant foundations only add to this problem.

Development of layered models for geotechnical centrifuge tests [PDF]

, 2018
Centrifuge modelling is an established technique for investigating the ground response to complex and non-standard geotechnical events. These models are usually made from re-formed soil, allowing for comparisons with naturally occurring soil deposits. Clay models are formed by mixing clay powder and water into a slurry.
