This short paper proposes time-series x-ray tomography as a valuable tool for quantifying freezing processes in a remoulded clay. As an example, three simple closed system (i.e., no water entry) experiments are performed and analysed, all of which were frozen under relatively high but different thermal gradients. The progressive appearance of a zone of ice-lenses, and the deformation of the sample due to freezing and cryogenic consolidation is quantified with time—with the hope of providing data to THM models, and to this end the data presented are made available online. The rich patterns in the frozen zone are also illustrated and discussed. The measurement technique used has satisfactory performance and further work on open systems, different materials and different thermal gradients is expected to contribute significantly to understanding of the complex phenomena surrounding freezing in soil.

这篇简短的论文提出了时间序列X射线断层扫描技术，作为量化重塑粘土中冷冻过程的有价值的工具。例如，三个简单的封闭系统（即（没有水进入）实验并进行了分析，所有实验均在相对较高但不同的热梯度下冷冻。随着时间的推移，量化了冰透镜区域的渐进外观以及由于冻结和低温固结而导致的样品变形-希望将数据提供给THM模型，并最终在线提供所提供的数据。还说明和讨论了冻结区中的丰富模式。所使用的测量技术具有令人满意的性能，并且有望在开放系统，不同的材料和不同的热梯度上进行进一步的工作，这将大大有助于理解围绕土壤冻结的复杂现象。
