The major early development of geotechnical modelling in the centrifuge occurred in the USSR following independent proposals made by Davidenkov and Pokrovskii in 1932. All other geotechnical structures are mechanically more complex, involving elements such as retaining walls, piles, anchors and/or external forms of loading other than soil body forces ...

Capillary Flow in the Geotechnical Centrifuge
Geotechnical Testing Journal, 1999Abstract A “bundle of capillaries” approach is used to model unsaturated soils. Movement of fluid is approximated by employing a simple Poiseuille's capillary flow mathematical model. It is found that the centrifuge model flow time is 1/n2 times that for the pertinent prototype flow time.

Soil Liquefaction Tests in the ISMGEO Geotechnical Centrifuge
2018Operational since 1988, the ISMGEO geotechnical centrifuge is a 240 g-ton centrifuge with a nominal radius of 2.2 m. The centrifuge can spin up a model of 400 kg up to 600 g. Since 2010 the centrifuge is equipped with a 1D shaking table able to reproduce real earthquake signals under an acceleration field up to 100 g.

Testing of Reinforced Slopes in a Geotechnical Centrifuge
Geotechnical Testing Journal, 1997Abstract An evaluation of the use of centrifuge modeling as a tool for analyzing the behavior of reinforced soil slopes is presented in this paper. A review of the state-of-the-art indicates that previous centrifuge studies have focused mainly on the performance of reinforced soil vertical walls and that limit equilibrium approaches ...

Creating seafloor conditions in geotechnical centrifuges
2005Soil models can be built in geotechnical centrifuges under specified procedures with good reproducibility between 40 and 100 % relative density. Nevertheless, many problems require model making with loose samples, especially when seafloor conditions are to be represented.

Development of a small-scale geotechnical centrifuge
International Journal of Physical Modelling in GeotechnicsOil sand fluid fine tailings in northern Alberta have very poor water-release characteristics and require many decades to fully consolidate under their own weight. Generally, physical and/or chemical treatments are necessary to improve the consolidation behaviour and manage the tailings in an economical and environmentally acceptable manner.

The ISMGEO seismic geotechnical Centrifuge.
2016The ISMGEO seismic geotechnical centrifuge (ISGC) is a medium size beam centrifuge, made up of a symmetrical rotating arm with a diameter of 6 m. The centrifuge has the potential of reaching an ac-celeration of 600g at a payload of 4 kN. In 2010 it was equipped with a 1-degree of freedom shaking table.

The Use of a Centrifuge in Geotechnical Engineering Education
Geotechnical Testing Journal, 1989Abstract Geotechnical centrifuges have been seen to date principally as research machines. A role is now suggested in which centrifuges of modest size and cost can contribute usefully to the education and training of geotechnical engineers in college laboratories.
