Abstract: | Heat source function method is adopted in the present paper to derive elementary solutions of coupled thermo-hydro-mechanical
consolidation for saturated porous media under conjunct actions of instantaneous point heat source, instantaneous point fluid
source and constant volume force. By using the so-called fictitious heat source method and images method, the solutions of
a semi-infinite saturated porous medium subjected to a local heat source with time-varied intensity on its free surface are
developed from elementary solutions. The numerical integral methods for calculating the unsteady temperature, pore pressure
and displacement fields are given. The thermomechanical response are analyzed for the case of a circular planar heat source.
Besides, the thermal consolidation characteristics of a saturated porous medium subjected to a harmonic thermal loading are
also given, and the fluctuation processes of the field variables located below the center of heat source are analyzed.
