| Research Abstract |
The compressive properties of soil mixed with deformable particles such as expanded plastic were examined and considered to make a model of the mechanical behavior from a particulate point of view by performing a series of rod-stack model tests. As a result, it was clarified that the volumetric compression added by deformable particles were classified into following three more components: 1) the volumetric compression of the deformable particles themselves, 2) the pore space reduction caused by the resultant deformation of the structural skeleton and 3) the pore space reduction caused by further relative movement of the deformed particles. And then, the numerical expression for theoretically estimating these components were proposed.
