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.
