Abstract: With the energy conservation as the clue, it reviewed some more complicated sand dilatancy equations, which are obtained through incorporating state parameter for homogeneous sand, and the state parameter and anisotropic state variable for transverse homogeneous sand, based on some simple version sand dilatancy equations such as Camclays, modified Camclays, and Rowes et al. It points out that initial fabric tensor and loadinginduced fabric tensor incorporated into sand dilatancy equation will be the main research aim in the future.

Key words: dilatancy equation; plastic potential; state parameter; homogeneity; transverse homogeneity
