In order to understand the phenomena and conditions that should be noted when evaluating the infiltration behavior of water in the buffer material during the re-saturation process of the engineered barrier system, Authors are working on a comparative evaluation of previous test results and coupled analysis results. The development status of the technology to evaluate the influence of thermal, chemical, and mechanical processes using coupled analysis is presented.
