Elastoplastic analysis of the nonlinear stage of behavior of a soil base
Conclusions 1. In an elastoplastic calculation of a base, it is expedient to use the Coulomb—Mohr criterion as the condition of plastic flow for upward yielding zones and the Tresca—Hill criterion for the core under the plate and deep zone. 2. Calculation of soil bases in the nonlinear stage of their behavior should be done with consideration of the process of localization of shear strain of the soil. 3. Reflection of the unstable character of deformation with a decrease of soil strength in the shear band is an important factor in determining the bearing capacity of dense sand bases.
