Abstract :
In this article, Thermo-Hydro-Mechanical (THM) response of saturated clays
has been studied. For this purpose, the nite element program PISA, which is able to
simulate coupled THM analysis, has been employed. Due to the e ects of temperature on
the mechanical behavior of soil, two temperature-dependent constitutive models have been
implemented in PISA. For veri cation of the developed numerical model, ATLAS large scale
experiment has been simulated in di erent conditions and the simulations results have been
compared with in-situ measurements. Comparison of predictions and measurements reveals
that by using coupled formulation along with thermoplastic constitutive models, the main
aspects of the THM behavior of saturated clays can be captured. The results indicate that
for accurate simulation of advection phenomenon, two-dimensional nite element model
should be used.
