  3. Abstract:
  4. In this paper the relation between dissipated energy and pore pressure is studied using 1 g shaking table test results. Toyoura sand is used for the physical models. Both one and two dimensional variable phase loadings are applied to the models. Shear work was calculated using accelerations and displacements and normalized to the mean effective stress. Pore water pressure was also normalized to the vertical effective stress. The results show that the pore pressure has a unique relationship to the shear work no matter whether the shaking is one or two dimensional. The results also show that the generated normalized pore pressure is independent of loading type and confinement. © 2006 Taylor & Francis Group, London
