In difficult engineering and geological conditions, the water-supporting elevated structure’s design is carried out taking into account the base soil model, as well as the correctly selected software package, which allows to determine the stress-strain state (SSS) of the structure and as a result, all structural and technological parameters qualitatively.

The presence of soils, subjected to consolidation, increases the risk of the additional sediment formation, which may affect the object stability in the base.

When designing objects in complex engineering and geological conditions, it is necessary to use a specialized geotechnical software package allowing to take into account the foundation soils nonlinear properties, as well as the specific occurrence of geological elements, since the current RF standards only take into account the nonlinear properties of the foundation in a simplified form.

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.

Identifying the type of damage in which the structure’s performance is not ensured is one of the most critical tasks in assessing the structures’ performance. The necessity of assessing the structure’s behavior for operability in the base - foundation - elevated system is proved.
