In the cement deep mixing (CDM) method, one approach to joint construction is creating a surface-contact joint. In this study, an unconsolidated-undrained triaxial compression test was performed on cement-treated soil specimens with joints artificially created by successive pouring. The effects of the presence or absence of such successive pouring joints on the strength of the specimens were then examined. The results showed that the compressive strength of the specimen decreased by approximately 0%30% with a successive pouring joint.
