Coupled thermo-hydro-mechanical analysis
In this thesis, the processes that take place in unsaturated soil at non-isothermal conditions are studied. Firstly, two devices have been modified: the thermo-hydro-mechanical (THM) column-type device and the oedometer device. Secondly, a new model for the hysteretic soil-water retention relationship, which occurred in the two-phase flow, is proposed. The model was validated by the numerical simulation of two-phase flow and against data from sand column tests. Thirdly, the study contributes to the identification of parameters for coupled THM analysis based on the back analysis approach. The study proposes a new strategy for identifying model parameters as well as assessing the reliability and accuracy of the identified model parameters. For sensitivity analysis of model-parameters, both local and global analyses are performed and the results are compared and critically discussed.
