DMM (Deep Mixing Method) is an effective soil improvement method. In this study, the indoor test was practiced with a model apparatus of mixing machine and the mixing mechanism was considered to investigate the relationship between soil properties and the resisting moment, penetrating resistance on mixing blade of mixing machine. From this investigation, the method was proposed to estimate the kind and the properties of original ground soil.
The field test was practiced with actual DM-machine to ascertain the results of the indoor test. Moreover, two methods, the measurement of density and water contents with Radio-Isotope, and the work-done analysis, were proposed and verfied to appraise the quality of treated soil in field. From these results, the possibility for electro-mechanical control in DMM is considered.
