ABSTRACT
A macroscopic mechanical model of saturated soils which are sensitive to chemical composition of pore fluid, coupled with transport of chemicals is developed. The methods of non-equilibrium thermodynamics and spatial averaging are applied in order to derive macroscopic description including balance equations, Gibbs equations and entropy production for mechanical or chemical loads. The constitutive relationships are proposed describing chemo-mechanical response of porous materials and reactive transport. Analytical solutions for 1D initial-boundary value problems are solved describing chemical consolidation and chemical stresses coupled with advective-dispersive transport in pore fluid.
