Open AccessScale dependency of anisotropic thermal conductivity of heterogeneous geomaterials
The precise determination of subsurface thermal properties is critical for ground-source heating systems. The geomaterials are inherently heterogeneous, and their thermal conductivity measured in laboratory an...

Effect of mesoscale internal structure on effective thermal conductivity of anisotropic geomaterials
Geomaterials tend to be stratified due to the geological process, and their properties are often anisotropic. In this study, the quartet structure generation set (QSGS) method is adopted to reconstruct the mes...

Coupled thermal–hydraulic modeling of artificial ground freezing with uncertainties in pipe inclination and thermal conductivity
Artificial ground freezing (AGF) has been widely used as a temporary soil stabilization and waterproofing technique in geotechnical practices (e.g., tunnel construction). Many sources of uncertainty exist duri...

A generalized model for effective thermal conductivity of soils considering porosity and mineral composition
Soils have a variety of mineral compositions. Although a number of thermal conductivity models have been developed for soils, few quantitatively investigated the effect of mineral composition. In this study, t...

A Design Framework for Spatial Variability in Cement-Treated Soft Clay in Deep Excavations and Underground Constructions
This paper summarizes some of the recent works on spatial variability of cement-treated clay for underground construction. The studies were conducted using deterministic and random finite element analyses, cal...
