In this study, it is aimed to determine the bearing capacity of the deep mixing columns belonging to five different projects, for which axial loading tests were carried out, by graphical and analytical methods and the results have been compared with each other. Three methods which are frequently used in the literature, were used to interpret the results of the loading experiments. These methods are: the Decourt, De Beer and Chin-Kondner. Axial loading tests were applied to the deep mixing columns in the field. For each project, loading was carried out based on the previously determined project load value. In the calculations based on the relationship between the load increase and the deformations, it was found that the bearing capacity values calculated with the Decourt and Chin-Kondner methods gave close results for the five projects. The bearing capacity values calculated with the De Beer method were relatively lower than the other methods.
