Micro X-ray CT imaging technology is effectively used in the field of geotechnical engineering as one of the useful tools to visualize the microscopic morphology of soil. On the other hand, the micromechanics model is one of the methods to construct the constitutive law of macroscopic mechanical behavior from the information on the micromorphology of soil. This study aims to obtain information on a wide range of soil micromorphology using super-resolution to derive a practical micromechanical model that considers the statistical nature of soil micromorphology. Here, we compare the three methods through simple numerical experiments and discuss the effectiveness in terms of their accuracy and possible extrapolation.
