Various geotechnical engineering problems have been studied mainly with continuum models so far. However, such modeling has not always resulted in sufficient solutions of the problems in comparison with the case of metals. On the other hand, it is clear from the history that the mainstream of Mechanics in general is not continuum mechanics but discrete mechanics dealing with material points or elementary particles. Recent development of computational science also requires more and more the discrete mechanics. Considering such circumstances it is worth exploring discrete granular models of geomaterials for the alternative engineering tool. This article reviews the past granular models of geomaterials putting emphasis on how these models connects micro behavior with macro behavior, and tries to make clear what is lacking now and where we should go in the future.
