Most previous investigations for consolidation-induced solute transport models have been limited to one-dimensional studies in unsaturated porous media and lack systematic parameter sensitivity analysis. This study addresses these gaps by analyzing the effects of hydraulic conductivity (K), shear modulus (G), saturation ( (Formula presented.) ), Poisson’s ratio ( (Formula presented.) ), partitioning coefficient ( (Formula presented.) ), and anisotropy ratio ( (Formula presented.) and (Formula presented.) ) on pore water pressure, soil deformation, and solute transport. The findings reveal that higher (Formula presented.) values significantly hinder solute migration through enhanced adsorption and reduced vertical transport to deeper layers, while increasing anisotropy ratios primarily enhance horizontal migration, with their effects diminishing beyond a threshold. Additionally, a higher K accelerates pressure dissipation and solute movement, while a lower G increases soil deformation and speeds up solute migration. Saturation has a minor effect on solute concentration, with slight increases under higher (Formula presented.). The Poisson ratio significantly impacts the transport of the solute, with smaller (Formula presented.) accelerating and larger (Formula presented.) slowing migration. These insights offer valuable theoretical support for optimizing models in unsaturated porous media.
