Outline of Final Research Achievements

In recent years, soil contamination due to toxic water-disolved materials has become one of the most serious environmental problems. Study for mobility evaluation to pollutants in saturated / unsaturated ground has been proceeded. In the analysis area, ground is assumed as soil / solution / dissolved material / air mixture continuum material. Applying the mixture theory to the conventional continuum theory, the theoretical model which ground deformation, pore fluid (solution and air) movement, and dissolved solute transport are evaluated simultaneously has been developed. Additionally, the one dimensional column test device equipping with the pore fluid pressure meter and flow measuring instrument was constructed to confirm the solute movement in the various condition of the ground.
