Abstract:

The article discusses the stress-strain state of Foundation of various forms. It is noted that for foundations on natural basis is traditionally used for the solution of Boussinesq (1885) about the force applied to the ground surface, i.сe. without taking into account the fact that the depth of the foundations, and the solution obtained Mindlin (1950) takes into account the fact that the depth of foundations, but does not consider the development of tensile stresses above the level of application of the load. The analysis of the Kelvin equation for concentrated force applied at an infinitely large depth. The analysis of the stress state of grounds for the buried foundations using solution of Kelvin indicates the possibility of its use in the case of the use of deep foundations.
