N2 - This paper presents an overview of recent numerical and experimental research conducted on consolidation-induced transport of contaminants in compressible porous media.The CST2 andCSTCRS1numerical models use a dual-Lagrangian framework to separately follow the motions of solid and fluid phases during consolidation and have the capability to simulate large strain compression with associated material and geometric nonlinearities. Transport processes include diffusion, dispersion, non-equilibrium sorption, and first order decay reactions. Large strain consolidation-induced transport tests were conducted on composite specimens of kaolinite slurry consisting of an upper uncontaminated layer and a lower layer contaminated with potassium bromide. CST2 simulations closely match the experimental data for a variety of loading and boundary conditions, including variable concentration and unload/reload effects. The research indicates that both diffusion and consolidation-induced advection processes can make important contributions to solute transport.
