| Abstract: |
| This work concerns the problems associated with a poroelastic half-space soil medium subject to a normal force within the context of generalized thermoelasticity with one relaxation time.By remaining faithful to Biot's theory of dynamic poroelasticity,the foundation material is idealized as a uniform,fully saturated,poroelastic half-space medium.The governing equations of thermo-hydro-mechanical dynamic model (THMD) is established,and this model can reduced into the thermo-elastic dynamic model (TMD).We then deduce the general solutions of non-dimensional vertical displacement,excess pore water pressure,vertical stress,and temperature distribution using normal mode analysis and depict them graphically.Throughout this paper,we discuss the differences between THMD and TMD. |
