- Abstract
A building or a construction is erected on the soil foundation. Its stability, reliability and operation are determined not only by design solutions, but also by soil properties. The main reason for load-bearing structures’ deformation is the uneven or excess foundations slumping. So, the primary problem of foundations design is fulfillment of condition, according to which the calculated deformations must not exceed the permitted values, limited with SP 22.13330.2011 specifications. The foundation slumping can be relatively determined only with the direct proportionality between stresses and deformations of soils, i.е. in non-subsiding soils. In subsiding soils the dependence between the working stress and deformation is of nonlinear character. To eliminate the subsiding properties of loess soil foundation, the presoaking method is used. The authors of the paper present the calculation procedure, which ensures the efficiency of presoaking, based on the approximate calculation scheme. In the case under consideration the method includes calculating additional slumping within the limits of the upper unconsolidated layer of the soaked foundation. The foundation is taken as a two-layer soil: the upper layer is unconsolidated subsiding soil and the lower base layer is consolidated non-subsiding soil, assuming that the vertical normal stress distribution in the presoaked foundation is linea
