Abstract

Recently, fluidization treated soils have come to be used as landfill materials or fillers in such landfill of underground space in Japan. However, the design and construction of the fluidization treated soils at present is based only on empirical knowledge. Therefore, taking into account the findings based on a theory is thought to be useful. In this study, it has evaluated the flow-ability of the fluidization treated soils based on the flow analysis by the MPS method and the experimental evaluation. Favorable results have been obtained in the numerical flow analysis by using the Bingham model to the MPS method. In addition, the authors have developed a fluidization treated soil with increased flow-ability (super-fluidization treated soil). It has evaluated from two aspects of mechanical properties and flow properties of the high flow of the super-fluidization treated soil. The flow properties show that it has a high flow-ability than the fluidization treated soil.
