Outline
Based on the multiphase microstructural morphological changes of soil particle, water and air phases, this study (1) models the strongly non-linear behaviour of soil with the fundamental physical quantities of soil mechanics and (2) models the inherent microscopic heterogeneity of soil as a granular material to the spatial variation of macro physical properties, thereby developing a technology for predicting geotechnical behaviour rooted in the physics of the soil particle and pore scale has been developed. Putting into practice recent innovations in experimentation, technology and theory: the extraction of micro-scale multiphase microstructural morphological changes using X-ray micro-CT and image analysis; the development of micromechanics-based models; and the modelling of heterogeneity by introducing data science.
