<abstract xmlns="http://www.w3.org/1999/xhtml"> The validation of the general stress-dilatancy relationship is shown based on biaxial compression test data presented in the literature under drained and undrained conditions. Rowe’s and Bolton’s relationships can be treated as simplified forms of the general stress-dilatancy relationship. The stress ratio values are a function of not only the dilatancy but also the intermediate principal stress, the non-coaxiality angle defined by Gutierrez and Ishihara and the stress-strain path. For many granular soils, the critical frictional state angle of the shearing resistance Φo = Φ′cv and parameters α and β are functions of the drainage condition, the stress level and the stress and strain paths.</abstract>
