In evaluating the behavior of near-field after emplacement of engineered barriers, it is necessary to understand quantitative changes of near-field over time and space. However, the coupled phenomena in near-field are complicated because thermo-, hydro-, mechanical, chemical process will interact, so that no comparison with real behavior will make it possible to find out if the applied model will represent the coupled behavior adequately or not. Hence, it is necessary to validate the model, based on the result of coupled behavior experiment in laboratory or in site. In this report, authors evaluated the applicability of coupled T-H model under the condition of simulated near-field, based on the results of coupled experiment in room. As a result, it has shown that the model which improved the fit to the measured data, is reasonable under this condition.
