In this paper, the thermo-poroelasticity theory fulfilling local thermal non-equilibrium condition (LTNE) is used to investigate the thermo-osmosis effect on one dimensional saturated poroelastic half space subjected to impact loadings. It has been reported in the literature that coupled flow known as thermo-osmosis by which flux is driven by temperature gradient, can significantly change the fluid flux in clay, argillaceous and many other porous materials whose permeability coefficients are very low. This study presents a mathematic model to investigate the coupled effect of thermo-osmosis in saturated porous medium. Analytical solutions of temperatures, pore pressure, stress, displacement and fluid flux are obtained by Laplace transform. Results for a typical clay are used to investigate the effect of thermo-osmosis. The effects of LTNE on temperatures, displacement and stress are also studied in this paper.
