| Abstract: | Three formulae are derived to determine the coefficient of earth pressure at rest for cohesionless soil by using the stress vector based constitutive model. In the constitutive model, the action effect of stress vector is decomposed into the action effect of mean effective stress and that of stress ratio vector(ratio of deviatoric stress vector to mean effective stress). The validity of these formulae are investigated. |

| Keywords: | stress vector stress vector based constitutive model cohesionless soil coefficient of earth pressure at rest |
