Abstract

In this paper, based on the chemo-thermo-poroelasticity model of saturated porous medium undergoing the local thermal non-equilibrium (LTNE) conditions, the pore pressure and chemo-thermal stresses around a spherical cavity in an infinite fluid saturated porous medium subjected to sudden variations for temperature and solute mole fraction on the cavity boundary are investigated by employing Laplace transform technique and numerical method. The results show that the pore pressure and stresses are dominantly affected by the chemical effect rather than the thermal effect when the temperature and variation of the solute mole fraction change together, and the LTNE effects on radial stress (magnitude) become very pronounced when Sp is small ( 0.35) and Bi is moderate ( 1.0). In addition, the pore pressure and stresses are always same order of magnitude whether considering the chemical effect or the chemo-thermal effect.
