Abstract

This paper presents results of a fluidity evaluation for fluidization treated soils using the Distinct Element Method (DEM). In recent years within Japan, fluidization treated soils have been frequently used as soil materials for land reclamation projects, backfilling underground spaces, etc. However, the design and mixing of fluidization treated soils is based on previous experiences applied to new situations. It is useful to consider the findings based the application of the DEM method to the fluidity assessment and theory of fluidization treated soil, which is the focus of this study. As a result, it was clarified that the fluidity of fluidization treated soil could be sufficiently reproduced by using the 3-D particle flow analysis with the DEM method.
