The historically developed geological conditions of Kazakhstan are characterized by the diversity of the composition of the geological profile. In most of the developed territory, conditions are represented by deposits of macroporous, loess soils of different moisture conditions. Construction on these soils requires a set of measures to strengthen and improve mechanical properties. The article discusses the application of the deep mixing method for strengthening compressible soils. However, the method is still limited in application. The main reason for the weak spread of the method is the quality of the soil-cement column material obtained by mixing and the effect of seismic action on its load-bearing capacity. Strengthening elements in the form of soil-cement columns are the main element that increases the bearing capacity of foundation soils. The article presents the results of a study of the physical and mechanical properties of column material obtained in the field by wet deep mixing. The results of studies of the DSM soil-cement column model, performed on a scale of 1:100, are presented. The models are strengthened by reinforcement with metal profiles or a frame of reinforcing bars. The reliability of the results obtained was verified by analytical calculations in a real geological profile.
