COUPLED HYDRO-MECHANICAL-CHEMICAL MODEL OF OSMOTIC CLAY SWELLING

摘要：

The new model of osmotic clay swelling is proposed. The model is intended for coupled description of rheological and transport behavior of clays. Model is founded on the classical methods of consolidation theory and chemical osmosis theory in clays (Greenberg model). The main improvement is concluded in using of the new equation for dynamics of clay swelling. Model contains from mass balance equation; mechanical equilibrium equation; rheological correlations; swelling equation. After solution of equations we investigated the features of our model, which are important for explaining of hydro-mechanical and chemical clays behavior. Our model permits to analyze a lot of interesting hydro-mechanical situations in real clay beds. Its also shown that obtained solutions are in a good harmony with the experimental data.
