| dc.description.abstract | Study of deep geological repository, many items must be evaluated to ensure the safety of the repository. In this study, using finite element software ABAQUS for analysis to discuss the temperature, saturation and effective stress in the repository.
First, this research refers to the BMT1B of DECOVALEX III project. By changing the porosity of the rock, to discuss the influences of temperature and saturation in the repository under different rock permeability. It is also aimed at the influence of the permeability parameter of the buffer material.
Secondly, in order to analyze the temperature, saturation and effective stress of the repository that the canister started to release heat at different times. Since analysis needs to be conducted on more than two canisters, the ＂representative volume element ＂ is not suitable for this analysis application, use the ＂multi-disposal holes ＂.
Finally, in order to simulate the problem of burying the canister, it must be considered that the material of the disposal tunnel is rock before burying. After buried, the materials in the disposal tunnel will become backfill, buffer and canister. The analysis needs to consider the changes of materials, which can better present the real situation. | en_US |
