摘要作为正在进行的国际DECOVALEX项目的一部分，四个研究小组使用五种不同的模型来模拟耦合热，水文和机械（THM）过程附近的废物处置漂移的地质核废物处置库。模拟进行了两个通用的处置库类型，一个与开放和其他回填处置库漂移，在较高和较低的封闭后温度，分别。在该项目完成的第一个模型初始阶段，一个很好的协议之间的研究团队在计算三卤甲烷反应的两种处置库类型，虽然一些分歧的水文响应目前正在解决。特别是，很好的协议，在基本的热机械响应实现了两种处置库类型，即使一些团队使用相对简化的热弹性热传导模型，忽略了复杂的近场热水文过程。复杂和简化的过程模型之间的良好协议表明，基本的热机械响应可以预测具有相对较高的置信度。
Abstract As part of the ongoing international DECOVALEX project, four research teams used five different models to simulate coupled thermal, hydrological, and mechanical (THM) processes near waste emplacement drifts of geological nuclear waste repositories. The simulations were conducted for two generic repository types, one with open and the other with back-filled repository drifts, under higher and lower postclosure temperatures, respectively. In the completed first model inception phase of the project, a good agreement was achieved between the research teams in calculating THM responses for both repository types, although some disagreement in hydrological responses is currently being resolved. In particular, good agreement in the basic thermal-mechanical responses was achieved for both repository types, even though some teams used relatively simplified thermal-elastic heat-conduction models that neglected complex near-field thermal-hydrological processes. The good agreement between the complex and simplified process models indicates that the basic thermal-mechanical responses can be predicted with a relatively high confidence level.
