In this paper, a method of porous media dispersed and theory of damage in continuom media mechanics are presented. The procedures in which the soild-skeleton stiffness degeneration of porous media and channel diversification of liquid movement are described by linking macro- and micro-mechanics of damage (the crack and void ratio) model. The model can be derived from REV(representative elementary volume) finite element analysis and experiment data. On the basis of conservation equation of continuum medium mechanics, the dynamic equation group of unsaturated soil is derived. Then the dynamic equation of saturated soil and one dimension consolidation equation can be degenerated easily.3figs.,11refs.
