Description
Summary:The development of new territories, as a rule, is complicated due to a preliminary preparation of soil foundations to improve their deformation properties. Modern preference is basically given to mechanical ways, namely to compaction of soil foundations. The development of new and elaboration of the existing models of soil deformation are promising directions in improvement and development of new technologies for mechanical compaction of soil foundations. Theoretical researches were performed to estimate the description adequacy of deformation in a dispersed non-cohesive soil with practical results by the existing models. A sandy soil was used as a sample of disperse non-cohesive soil for which a deformation characteristic was defined in laboratory conditions. The comparative analysis of theoretical and experimental data allowed us to estimate approximation adequacy of results for laboratory studies of a sandy soil deformation for the examined models. The maximum value of a relative error of laboratory data approximation for this model did not exceed 0.145. According to results of conducted studies, a model of a dispersed non-cohesive soil deformation is proposed. Coefficients k8...k10 of the given relationship are to be calculated according to the results of compression tests of simulated dispersed non-cohesive soil in the operating pressure range.
