Experimental Substantiation of Internal Strength Parameters of L. N. Rasskazov’s ≪Energy≫ Soil Model

The article presents a method for determining the internal strength parameter of soil in triaxial tests of L. N. Rasskazov’s ≪energy≫ model, which describes the soil stress state in conjunction with the energy accumulation of volumetric and shear deformation on various loading trajectories. The results of comparing the energy parameter of soil strength with the Coulomb-Mohr strength parameter are presented, while the limits for using the Coulomb-Mohr strength parameter under conditions of predominantly plastic deformation are discussed.
