| abstracts | In the paper an empirical method of determination of elastic constants of non-cohesive soils on the basis of the experimental data from conventional triaxial compression tests, is proposed. The method is based on a new interpretation of triaxial tests during which samples of dry sands are subjected to several cycles of loading and unloading. The test results of all strain and stress components measured in the experiment are presented in terms of deviatoric stress versus deviatoric strain and mean effective pressure versus volumetric strain diagrams. It is assumed that after any stress reversals the material exhibits purely elastic response that obeys Hooke's linear law. Elastic moduli are determined from the first stage of unloading, which is different from the other methods commonly accepted in soil mechanics. The main advantage of the method proposed was isolating linear behaviour of the material that corresponds to elastic response and including in the analysis the lateral deformation of a sample. In the paper several examples of test results for various confining pressures and initial void ratios are presented and analysed. Comparison with other methods is made and discussed. |
