Many problems that arise during construction and design of earth hydroengineering complexes, including those such as estimating the bearing capacity of an inhomogeneous base, determining the lateral pressure of the soil, determining the criterion of crack formation in the cores of dams, estimating the stability of the slopes of structures and so on, cannot be resolved confidently when conducting ordinary model experiments with full-scale soils. The main reason for this is that the stresses due to the natural weight in the models are considerably less than those in real structures: at the same time, as shown by investigations of many authors, the deformation and strength properties of soils under small and large stresses may differ considerably and not only quantitatively but qualitatively as well. To overcome this difficulty permits the use of the centrifuge modelling method in investigations, the main advantage of which is the possibility of investigating relatively small models made of full-scale soil under stresses similar to full-scale in absolute value and by the nature of distribution. This report goes into detail concerning this modelling technique.
