英文摘要	Based on the framework of elastic theory for unsaturated porous medium and considering the effects of non-isothermal conditions, this paper studies the influences of thermophysical properties on the attenuation characteristics of thermoelastic body waves in unsaturated soil. Firstly, the present work introduces the dispersion equations of thermoelastic body waves for three-phases unsaturated porous media. Secondly, the dispersion equations of thermoelastic body waves are theoretically solved by using a commercial math software. Finally, the evolutions of the attenuation coefficients of various thermoelastic body waves are analyzed by means of some numerical examples. The results demonstrate that the thermal expansion coefficient presents a great influence upon the attenuation coefficients for P-1 and thermal waves; the thermal conductivity just results in a significant change in the attenuation coefficient of thermal wave, while the attenuation coefficients of all thermoelastic body waves except for P-2 wave are very sensitive to the change of medium temperature.
