Response of different soils to dynamic loading is of a fundamental interest in many engineering, geophysical and environmental studies. Many methods have been proposed to estimate dynamic stability of soils. In this research one more approach based on laboratory cyclic testing is discussed. In such tests not only the specific features of examined soils, but also different conditions of static and dynamic loading can be taken into account. Analysis of the obtained experimental data explicitly supports the hypothesis of a logarithmic relationship between axial deformation of soil in cyclic triaxial compression and number of loading cycles. Evaluation of soil deformation under vibrodynamic loads can also be based on energy approach recently developed by one of the authors. Using critical amount of energy dissipated by soil per its unit volume has been proved to be reliable even in low dynamic stress range. Convergence of the proposed solution was proved using field measurement and observations. The proposed approach has been applied to evaluate additional settlements of structures founded on the bases with different soil profile and under various static and dynamic loading conditions
