Abstract

A model for mechanical behaviour of saturated-unsaturated porous media is presented within the framework of thermodynamics of irreversible processes. It includes interfaces with thermodynamic properties between the constituents. The necessary balance equations are derived using averaging theories. Restrictions on the form of the constitutive equations are obtained by exploiting the entropy inequality according to the Coleman-Noll procedure. A particular form of the governing equations is then solved numerically. The validation of the model proposed through a comparison between experimental and numerical results and an application example concerning a tunnel fire conclude the paper.
