Abstract: 
Considering the thermal contact resistance and elastic wave impedance at the interface, in this paper we theoretically investigate the thermo-hydro-mechanical (THM) coupling dynamic response of bilayered saturated porous media. Fractional ther-moelastic theory is applied to porous media with imperfect thermal and mechanical contact. The analytical solutions of the dynamic response of the bilayered saturated porous media are obtained in frequency domain. Furthermore, the effects of fractional derivative parameters and thermal contact resistance on the dynamic response of such media are systematically discussed. Results show that the effects of fractional derivative parameters on the dynamic response of bilayered saturated porous media are related to the thermal contact resistance at the interface. With increasing thermal contact resistance, the displacement, pore water pressure and stress de-crease gradually.
