Geotechnical Centrifuge Modeling of Chloride Diffusion through Soils [PDF]

International Journal of Geomechanics, 2012
Geotechnical centrifuge modeling provides a means of accelerating the transport of contaminants through a soil matrix. Contaminant transport mechanisms occurring in the geotechnical centrifuge model can be used to verify various mathematical and ...

Water supply to a geotechnical centrifuge

International Journal of Physical Modelling in Geotechnics, 2013
The supply of water to a centrifuge experiment has always been important. This paper details a new system which has been successfully commissioned for use on the geotechnical centrifuge at University of Cambridge. High water pressures and large flow rates were delivered to an experimental package, for the modelling of water injection-aided pile ...

AFCESA Geotechnical Centrifuge

1993
Abstract : The objective of this project was to compile a user's manual for the Air Force Civil Engineering Support Agency geotechnical centrifuge. In the process it was also necessary to upgrade the centrifuge to a state-of-the-art geotechnical research facility.

Staged Embankment Construction in Geotechnical Centrifuges

Geotechnical Testing Journal, 2023
ABSTRACT This study develops a novel apparatus to simulate the staged, automatic construction of embankments in geotechnical centrifuges with improved measurement accuracy. Modular test equipment was designed to incorporate the functionality of controllable and precise sand release; its structural components include a box-like sand ...

Drum Centrifuge for Geotechnical Research

Geotechnical Testing Journal, 1984
Abstract The use of a drum centrifuge for geotechnical research is described. This type of centrifuge is distinguished by its ability to carry a payload around the entire circumference of a rotating drum. This allows the formation of “endless” slopes and gives the centrifuge a large capacity at very low cost.

Geotechnical centrifuges

2010
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 ...

The Geotechnical Centrifuge in Offshore Engineering

Offshore Technology Conference, 1996
Abstract One of the greatest needs in offshore geotechnical engineering is for large scale test measurements on which to calibrate design procedures. The geotechnical centrifuge offers at least a partial remedy. Because it allows one to properly simulate stresses, it is a legitimate, relatively inexpensive option to

Capillary Flow in the Geotechnical Centrifuge

Geotechnical Testing Journal, 1999
Abstract 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.

Testing of Reinforced Slopes in a Geotechnical Centrifuge

Geotechnical Testing Journal, 1997
Abstract 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 ...
