Abstract: Centrifugal model testing, pioneered by the U.S. Bureau of Mines, developed in the USSR, and advanced in both gland and Japan, has been used to provide a realistic approach for solving complex soil mechanics problems. The basic concept of this testing technique is to create a scale model similar in every respect to a prototype and to subject the model to an acceleration such that the increase in self-weight stresses is equivalent to those at corresponding points in the prototype. With this method, the investigator can observe, in a short period of time, a sequence of events that is analogous to that occurring in the prototype over a long period of time. Published work concerning the theoretical and practical application of the centrifugal model testing was reviewed and documented. Various devices and techniques used in centrifuge model testing were studied. The feasibility of a centrifugal testing facility at the U.S. Army Engineer Waterways Experiment Station (WES) was examined. Major advantages and limitations of the modelling technique were also discussed in this study. Based on the review of literature and the large number of centrifugal testing facilities being used around the world, soil modelling using the centrifuge is technically attractive and appears to have great potential for solving geotechnical problems that cannot be solved adequately by conventional means. WES offers an ideal environment for the establishment of such a facility.
