STUDY OF CREEP OF SAND

Statement of the problem. Subgrade has perceived rheological properties, most importantly, creep. As a result, the number subbase displacements and their irregularities grow constantly in re-cent years. But this fact is not taken into account in calculations, this is why additional studies of structural strength and creep of sand are essential.Results. Empirical relationships between displacements of models of sand subbase and loading conditions are obtained. It is shown that creep in sand subbase develops within a few months and years even. A degree of an increase in strength of sand with low moisture content with time result-ing from structural strength formation is examined. It is found that a deformation rate depends largely on a loading level.Conclusions. The data obtained allow us to develop more reliable methods to predict a defor-mation change with time.
