Visual performance evaluation of relative agitating type of deep mixing method by computer simulation and agitation model experiment

One of the common issues related to the ground improvement methods is that it is difficult to properly design and manage the construction process of improved soil body because the condition inside the target ground cannot be directly confirmed (visualized) during the construction. if the target ground can be modeled using a computer and the excavation and agitation can be reproduced by the ground improvement method, it is possible to predict what kind of ground improvement is performed in the target ground. As the result, more efficient ground improvement can be considered. In this study, the process of excavation and agitation is three-dimensionally modeled on a computer, and the behavior inside the target ground and its influence on the surrounding ground are visualized. The purpose of this is to evaluate the excavation and agitation by the DCS blades while confirming the condition inside the target ground. For the purpose of experimentally and visually confirming the condition of excavation and agitation by the DCS blades, an excavation and agitation model experiment by the DCS blades using pellets colored in each color is carried out.
