Abstract
This paper considers a modification of
the "predictor" stage of Godunov's
discontinuity decay method for problems
of nonlinear deformation of soft soils.
Soil behavior is described by the
Grigoryan's taking into account
nonlinear diagrams of volumetric
deformation, shear strength, and
plasticity. Assumptions are formulated
that reduce the auxiliary problem of the
decay of a discontinuity in soils to the
well-known problem that has a unique
solution. Examples of numerical
calculations are given.
