A dynamic three-phase coupled analysis is newly proposed. The equations governing the dynamic deformation of unsaturated soil are derived here based on porous media theory and constitutive models. The weak forms of the momentum balance equations of the overall three-phase material and the continuity equations (mass and momentum balance equations) of the pore fluids (water and air) at the current configuration are implemented in a finite element model. The discretized equations are solved by fully implicit method and the skeleton stress is also implicitly integrated. Predictions of the seismic responses of an actual fill slope during a future earthquake are performed under different moisture conditions of unsaturated fill.
