在过去的几十年里，人们一直在研究土壤介质中的热孔压。已有研究表明，温度变化对深层粘土中的热孔压有显著影响。此外，热载荷还会引起应力变化和热变形。建立了热孔弹性本构模型和先进的热孔弹塑性本构模型，并用数值方法模拟了热-水-力学过程。然而，土壤介质在THM过程中的准确响应还没有完全被理解。尽管数值模拟合理地预测了实验观测，但它们仍然不能用来完全证明现场观测的合理性。在本研究中，将热孔弹性模型的主要特征融入到热孔弹塑性本构模型(ACMEG-T)中，以进一步研究不同的热物性和水力特性对土壤介质热流体力学(THM)响应的影响。
Thermal pore pressurization in soil media has been investigated for the past few decades. It has been shown that temperature variations may significantly affect thermal pore pressure in clay soils confined deep into the ground. Moreover, thermal loading may lead to stress change and thermal deformation. Thermo-poroelastic and advance thermo-poroelastoplastic constitutive models have been formulated and incorporated numerically to simulate the thermo-hydro-mechanical process. However, the accurate response of soil media during THM process has not been completely understood. Although numerical modelling reasonably predicts the experimental observations, they still could not be used to completely justify the field observations. In this study, the main features of the thermo-poroelastic model are incorporated in a thermo-poroelastoplastic constitutive model (ACMEG-T) to further investigate the effect of different thermal and hydraulic properties on thermo-hydro-mechanical (THM) response of the soil media.
