The centrifuge is a useful apparatus to model geotechnical problems. In principle the soil stresses in the centrifuge model are similar to the stresses in the soil of the prototype situation. The correspondence of the stresses in the model are important in geotechnical problems since the mechanical behavior of soils is strongly dependent on the stress level of the soil. The types of sand which have been used in the research show indeed the indicated stress dependent mechanical behavior. The stress dependent behavior of the sand is visible in the footing tests. Here the confining pressures of the soil have been increased with increasing test accelerations. The footing tests at lower accelerations give a relatively stiffer resistance than footing tests at higher accelerations.
