本文提出了一个热-水-力学框架来模拟Boom粘土的干燥行为。首先，实验活动进行Noémie总理简要介绍，因为它是用来验证模型。由于使用X射线显微层析成像能够更准确地比较实验和数值应变场，因此强调了数据采集和处理。介绍了不同的子模型。进行数值模拟，以说明所提出的模型再现所观察到的行为的能力。最后，对与保水曲线和介质渗透率相关的几个关键模型参数进行了全面的敏感性研究，以更好地了解耦合模型背后的物理特性。
This paper presents a thermo‐hydro‐mechanical framework to model the drying behavior of Boom clay. First, the experimental campaign conducted Noémie Prime is briefly presented because it is used to validate the model. The data acquisition and processing is emphasized because of the use of X‐ray microtomography to be able to more accurately compare experimental and numerical strain fields. The different submodels are introduced. Numerical simulations are performed to illustrate the capability of the proposed model to reproduce the observed behavior. Finally, a comprehensive sensitivity study on several key model parameters associated with the water retention curve, and the permeability of the medium, is performed to get a better understanding of the physics behind the coupled model.
