Abstract: The achievement of this research is the fundamentals of a 3-D dynamic consolidation with governing equation established on the basis of transient dynamics theory ,characterized by drawing into it the effective stress and physical states dynamic constitutive relation and coupling the dynamic response and dynamic consolidation, static stress and dynamic stress, pore water pressure generation, pore water pressure diffusion, dissipation with each other so that to simulation the true process of stress-strain response of soil mass and to form a complete theoretical framework system of the seismic response analysis approach based on effective stress and physical states of soil mass. This method can reflect the shear dilatation-contraction real behaviors of saturated soil road foundation under earthquake; and it is more reasonable than usual static-dynamic alternate analysis method by finite element method.

Key words: effective stress, physical state dynamic constitutive relationship, transient dynamics theory, seismic response analysis, coupling analysis, finite element method
