Prediction of the Non-Isothermal Shrinkage of Natural Clay through a Fully Coupled Thermo-Hydro-Mechanical Model
Publication: Geo-Congress 2023
ABSTRACT
Underground geo-structures and climate change can trigger heat, moisture, and vapor flow and may induce volumetric shrinkage in clays. This drying phenomenon is a multiphysical process and is accompanied by alterations in the thermal, hydraulic, and mechanical states of the multiphase system. Reversible and irreversible characteristics of shrinkage deformation have been observed experimentally in clayey for different ranges of moisture contents. An accurate evaluation of the drying process helps to study the drying-induced damage of geomaterials. In this study, a finite element model that considers the thermo-poroelastoplastic constitutive framework is developed. The developed thermo-hydro-mechanical (THM) model can accurately analyze the transversely isotropic behavior of natural clays in unsaturated conditions. Results indicate that 82% of the total volumetric deformation in dying-induced shrinkage is irrecoverable. In addition, it is observed that most of the plastic volume change occurs within the early stage of drying when the soil’s unsaturated condition is in a funicular state.
