Chemically induced deformation of a porous layer coupled with advective-dispersive transport. Analytical solutions

In this paper a chemically induced deformation of porous material taking pl ace during advective-dispersive transport of a chemical is considered. Line arized governing equations are derived and analytical solutions of 2 one-di mensional problems for a homogeneous layer with drained boundaries are deve loped. Numerical results for a particular clayey material and a chemical mi grating through the layer showing distributions of concentration of chemica l, changes in porosity of the material and pore fluid pressure, and evoluti on of settlement of the layer as functions of time are discussed.
