Abstract

Consolidation-induced solute transport is an important process for a variety of engineering applications involving contaminated soil and other compressible porous media. This note presents a benchmark problem and numerical solutions for solute transport caused by one-dimensional consolidation of a saturated contaminated soil layer under large strain conditions. The solutions describe solute breakthrough and concentration profiles and can be used to check the accuracy of other analytical and numerical models. With regard to consolidation, the solutions account for vertical strain, soil self-weight, nonlinear constitutive relationships, and changing material properties during the consolidation process. With regard to solute transport, the solutions account for advection, diffusion, dispersion, and linear equilibrium sorption.
