Abstract: An analytical method is derived for the thermal consolidation of a hollow cylinder saturated porous medium with infinite length. In the coupled governing equations of linear isotropic porous thermoelastic medium, the influences of thermo-osmosis effect and thermal filtration effect are introduced. The solutions in Laplace transform space are first obtained and then numerically inverted by Stehfest method. These solutions consider the variable thermal loading and variable mechanical loading applied on the inner and outer pervious surface of the hollow cylinder with time. Finally, the evolutions of temperature, pore water pressure and displacement along radial direction with time are analyzed by a typical numerical example

Key words: saturated porous medium, hollow cylinder, thermo-osmosis effect, thermal filtration effect, analytical solution
