چکیده مقاله
In this research, an in situ field experiment called ATLAS carried out by François et al 1 is simulated by means of a Finite Element program capable of conducting coupled Thermal Hydro Mechanical analysis When a heat source is buried in the soil, the increase in the temperature causes excess pore water pressure The behavior of the soil is also affected by the change in temperature In this paper, using a new Thermoplastic constitutive model developed by Abuel Naga et al 2 , the effects of a buried heat source in the soil is modeled, and the numerical results are compared with the experimental data obtained from ATLAS experiment In addition, the effect of temperature on the volumetric thermal expansion coefficient and viscosity of water is considered, leading to more accurate results compared to the results of simulation with the original constitutive model assuming of temperature independent volumetric thermal expansion coefficient and viscosity for water
