Damage to individual structures or their elements at water structures can lead to irreversible consequences with significant damage and tragedies. The influence assessment degree of the plastic deformations, local subsidence of soil on the structure performance is an urgent task that requires attention.

Taking into account the nonlinearity of the soil during geotechnical calculation, including modeling the base stiffness, makes it possible to correctly determine the structures’ stress-strain state (SSS), as well as to consider their work in the base – foundation – structure system.
