'Geotechnical centrifuge modeling' is a technique for testing physical scale models of [[geotechnical|Geotechnical Engineering]] systems such as natural and man-made slopes and earth retaining structures and building or bridge foundations. The scale [[Physical model|model]] is typically constructed in the laboratory and then loaded onto the end of the centrifuge, which is typically between 0.2 and 10 m in radius. The purpose of spinning the models on the centrifuge is to increase the g-forces on the model so that stresses in the model are equal to stresses in the prototype. For example, the stress beneath a 0.1 m deep layer of model [[Soil mechanics|soil]] spun at a centrifugal acceleration of 50 g produces stresses equivalent to those beneath 5 m deep prototype layer of soil in earth's gravity.
