This paper presents the results of analytical simulations of in-situ test of engineered barriers system conducted at the Horonobe Underground Research Laboratory. This results is one of the tasks of the current phase "DECOVALEX-2023" of the international joint project DECOVALEX in which JAEA participates. Research teams from 6 countries or region, including JAEA, are participating in this task, Different analytical approaches and their effects on the analytical results are introduced, as well as the factors that affect the evaluation of coupled phenomena in engineered barrier system obtained through the task.
