In the application of a deep cement mixing method to spread foundation for buildings, there are some concerns about 1) scattering of the strength of improved soil columns caused by variations of the soil profile, 2) treatment of vertical distribution of the strength of improved soil columns, and 3) stability in quality of improved soil columns on construction control. This paper describes the relationship between the coefficient of variation of the internal strength of improved soil column in different soil conditions and the strength of full-size columns, and stability of the coefficient of variation as an indicator of construction qualities. The quality of improved soil columns applied to spread foundation for buildings is discussed through case study where the deep cement mixing method was used for both preventing liquefaction and ensuring bearing capacity.
