The Geotechnical Engineering and Geomechanics group in CEAE has developed world-class experimental and computing facilities that includes a state-of-the-art centrifuge laboratory used for research, industry design, and instructional purposes. The facilities include three geotechnical centrifuges. The largest, a 400 g-ton centrifuge, is one of the most powerful in the world. It is capable of accelerating a 4,000 lb payload to a maximum of 200 g in about 14 minutes, and can simulate earthquake motions in flight by utilizing a servo-hydraulic shake-table. The machine is used for numerous research projects investigating the static and seismic performance of retaining structures and slopes, seepage mechanisms, contaminant transport, and offshore foundation structures.
The facilities also include a 15 g-ton centrifuge, which has a symmetrical arm comprised of aluminum sections carrying swing-baskets at each end. The 15 g-ton centrifuge accommodates experimental payloads up to 18 x 17.5 x 23 inches and will accelerate a payload of 300 pounds up to 200 g. This mid-size centrifuge is currently being renovated to be used as a centrifuge permeameter. Please contact Prof. John McCartney (CEAE) for information regarding these facilities.
