Chemically induced deformation of a porous layer coupled with advective-dispersive transport. Analytical solutions. (English) Zbl 0999.74046
Summary: We consider a chemically induced deformation of porous material taking place during advective-dispersive transport of a chemical. Linearized governing equations are derived, and analytical solutions of one-dimensional problems for a homogeneous layer with drained boundaries are obtained. Finally, we give numerical results for a particular clay material and for chemical migrating through the layer. The results allow to study distributions of concentration of chemical, changes in porosity of material and pore fluid pressure, and evolution of settlement of the layer as functions of time.
