Біо) та шаруватою ґрунтовою основою з використанням: символьних розв’язків задач для переміщень поверхні основи; методів розв’язку динамічних контактних задач зі змішаними граничними умовами методом ортогональних поліномів Head Hrinchenko Viktor T., д.ф.-м.н.

Establishing patterns between the characteristics of the scattered field and the parameters of the elements structures and physical characteristics of the environment are the basis for the construction of both methods of condition control and safe operation of the object, as well as the ability to manage processes wave generation due to changes in physical and geometric characteristics. popup.description2  The problems of modeling the interaction of shallow foundations (square and round in plan, generally elastic) with an elastoplastic soil base are considered, both for structures and as part of vibration equipment when studying the reaction of a complex soil base during static and dynamic tests. The contact conditions, forces in the foundation slabs, zones of plastic deformation under the foundation are determined. To prevent the influence of reflected waves, artificial attenuation (according to Rayleigh) is used at significant distances, etc. For hydraulic and soil structures, the problems of stability of slopes and slopes with a quantitative assessment of the reserve and identification of possible shear zones are considered.
