ATLAS III小规模原位加热试验旨在评估由于放射性、放热废物的地质处置而在该寄主岩石中产生的显著温度梯度对Boom粘土的热-水力-机械(THM)影响。本文给出了实验过程中测得的温度、孔压和总应力的数据，并重点介绍了关于Boom粘土中的热各向异性和THM耦合的几个有趣的观测结果。该试验具有简单的几何结构和明确的边界条件，便于测量和数值模拟研究之间的比较。这些研究包括测试的三维耦合THM建模。温度和孔压的测量结果与数值模拟结果吻合较好，得到了一组THM参数，证实了Boom粘土的热力各向异性。
The ATLAS III small scale in situ heating test aimed at assessing the thermo-hydro-mechanical (THM) effects on the Boom clay of the significant temperature gradients generated in this host rock as a consequence of the geological disposal of radioactive, heat-emitting wastes. This paper presents data on temperature, pore water pressure and total stress measured during the experiment and highlights several interesting observations regarding the thermal anisotropy and THM coupling in the Boom clay. The test has a simple geometry and well defined boundary conditions, which facilitates the comparison between measurement and numerical modeling studies. These studies included three dimensional coupled THM modeling of the test. The good agreement between measurement and numerical modeling of temperature and pore water pressure yields a set of THM parameters and confirms the thermo-mechanical anisotropy of the Boom clay.
