乏核燃料的地质处置通常使用多重屏障系统的概念。为了预测这些屏障的性能，已经开发了数学模型，并根据国际DECOVALEX III项目中的分析解决方案，实验室测试和现场实验进行了验证和验证。这些模型一般考虑处置库周围地质介质中普遍存在的热（T）、水力（H）和机械（M）过程的全面耦合。对于DECOVALEX III项目的基准测试1号（BMT 1），七个多国研究小组研究了耦合THM过程对近场假设核废物处置库安全性的影响，并在本期的三篇随附论文中提出。本文是三个配套文件，它提供了BMT 1的概念化和表征，以及一些一般性的结论的基础上的数值研究的结果。它还显示了建立信任的数学模型的过程中，通过校准与参考T-H-M实验与现实的岩体条件和膨润土的性质和测量输出的热，水力和机械变量。
Geological disposal of the spent nuclear fuel often uses the concept of multiple barrier systems. In order to predict the performance of these barriers, mathematical models have been developed, verified and validated against analytical solutions, laboratory tests and field experiments within the international DECOVALEX III project. These models in general consider the full coupling of thermal (T), hydraulic (H) and mechanical (M) processes that would prevail in the geological media around the repository. For Bench Mark Test no. 1 (BMT1) of the DECOVALEX III project, seven multinational research teams studied the implications of coupled THM processes on the safety of a hypothetical nuclear waste repository at the near-field and are presented in three accompanying papers in this issue. This paper is the first of the three companion papers, which provides the conceptualization and characterization of the BMT1 as well as some general conclusions based on the findings of the numerical studies. It also shows the process of building confidence in the mathematical models by calibration with a reference T–H–M experiment with realistic rock mass conditions and bentonite properties and measured outputs of thermal, hydraulic and mechanical variables.
