The consolidation solutions of a saturated porothermoelastic cylinder

A coupled thermo-hydro-mechanical consolidation theory is proposed for a saturated porous cylinder with infinite length. The expressions of the field variations in Laplace transformation space are deduced such as temperature, pore pressure, volumetric strain, radial displacement, strain and stress, etc. Then, the time domain solutions are obtained by a numerical inversion scheme. Using the solutions, the evolution processes of thermal consolidation for a cylinder under axisymmetric conditions are studied for both constant and variable thermal loading conditions. These analytical results can provide some reasonable explanations for experimental results.
