Visual evaluation of relative deep mixing method type of ground-improvement method
One of the common issues related to ground-improvement methods is the difficulty of properly designing and managing the construction process of the improved soil body because the conditions inside the target ground cannot be directly confirmed (visualized) during the construction. If the target grou...

One of the common issues related to ground-improvement methods is the difficulty of properly designing and managing the construction process of the improved soil body because the conditions 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 a ground-improvement method, it will then be possible to predict what kind of ground improvement should be performed in the target ground. As a result, more efficient ground-improvement works can be considered. In this study, the process of excavating while agitating by the deep cement stabilization method (DCS method), whereby one of the ground-improvement methods is three-dimensionally modeled on a computer, is presented, and the behavior inside the target ground and its influence on the surrounding ground are visualized by MPS-CAE analysis. The objective of this process is to evaluate the excavation and agitation by the DCS method while confirming the conditions inside the target ground. For the purpose of experimentally and visually confirming the conditions while excavating and agitating by the DCS method, an excavation and agitation model experiment by the DCS method is conducted using a variety of colored pellets. |
