Accurate model tests of problems in soil mechanics may be carried out by the technique of centrifugal modelling, which preserves the correct magnitude and distribution of stress in the soil. There is a consistent set of rules to relate the behaviour of a full-size prototype to the behaviour of a model, not only for static tests, but also for dynamic events. The object of this investigation was, firstly, to show that dynamic modelling was possible, and secondly, to use the technique for some initial studies of soil-structure dynamic interaction and earthquake motion. The project used the geotechnical centrifuge at Cambridge University, England, and this will accept packages of almost one tonne in mass at a maximum acceleration of 155 g.
