Abstract
The coupled thermal-hydro-mechanical (THM) analysis of saturated porous media is of great significance and has been widely used in various engineering fields. However, the classical Biot theory assumes that the physical parameters of porous media are constant and ignores the influence of pore size on wave propagation characteristics, which cannot reflect the actual situation. Based on the nonlocal theory and Biot wave equation, a nonlocal coupled Biot THM dynamic model for porous media with variable physical properties is established by introducing the temperature-dependent factor function. Utilizing the nonlocal coupled Biot THM theory, the dynamic response of forced convection in a half-space saturated porous media under surface harmonic thermal action is investigated in this paper. The analytical solutions of temperature increment, displacement, stress, and pore water pressure of saturated porous media are obtained by means of differential operator decomposition. In addition, the effects of the temperature-dependent factor and porosity on the nonlocal model at different frequencies, and the effects of the nonlocal parameter on the distribution rules of various physical fields at different frequencies are explored in depth.
