Earthmoving in minature

Abstract This paper has described a similitude approach to earthmoving, using small-scale models based on a dimensional analysis with certain simplifying assumptions. An earthmoving mechanics laboratory has been developed, with facilities for testing two sizes of models. Despite the variability of real soils, and the complexity of the soil action during earthmoving processes, the somewhat idealized model tests are useful and exceedingly realistic. Models yield design information that is not available by any other means. Full-scale testing is still needed for final evaluation of an actual machine.
