Abstract
This contribution presents simulation of the Mock-Up test performed by CIEMAT (Madrid, Spain) [1]. The numerical model employs enhanced Barcelona Basic Model [2] coupled with water retention behaviour and water transport as given in [3,4]. In addition, the used theoretical framework takes full consideration of the thermal effects on the behaviour of bentonite. All the parameters in the simulation have been chosen based on experimental data [3,5,6].
The calculation is performed in custom Finite Element code build at Aalto University [4]. The calculated results are in good agreement with the experimental measurements validating the correctness of the implementation of the code. This study also confirms that a realistic estimation of the thermo-hydro-mechanical parameters is essential for a better prediction of the system behaviour in the physical reality.
