Thermo-Hydro-Mechanical Response of a Transmission Tower Pile Foundation in Seasonally Frozen Ground

Investigating the moisture-temperature-deformation interaction in geogrid-reinforced loess under cyclic freezing and thawing

Frost heave and thaw settlement from cyclic freezing and thawing (F-T) damage infrastructure like roadbeds in cold regions. Geogrids can help control this damage, but their mechanism in complex F-T processes is unclear. This study uses lab tests to examine how geogrids affect moisture, temperature, and deformation in l...

Temperature Field and Soil Deformation of Seasonally Frozen Embankment Section Under River Operating Water Levels

The stability of engineering structures in frozen regions is primarily governed by the coupled evolution of temperature, moisture migration, and stress fields driven by freeze–thaw cycles. In this study, a typical embankment section in Heilongjiang Province, a seasonally frozen region of China, is selected as a case st...

Multiphysical Modelling of Pile Behaviour Under Combined Vertical and Lateral Loads in Thermally Variable Soils

Investigation of Failure Mechanisms and Performance Optimization of Channel Seepage Control Layers in Cold Regions Under Coupled Wetting, Drying, Freezing, and Thawing Cycles

To address the degradation of seepage-control linings and structural instability of water-conveyance channels under coupled wetting-drying-freeze-thaw conditions in cold regions, this study investigated rehabilitated channels founded on expansive mudstone in northern Xinjiang. A two-dimensional transient finite-element...

Numerical analysis of Freeze-Thaw effects on geosynthetic-reinforced soils

Freeze-thaw (F-T) cycles induce road degradation in seasonally affected regions by causing frost heave, thaw settlement, and overall structural deterioration. This study investigates the role of geosynthetics in improving road resilience under F-T conditions through numerical modeling. A coupled thermo-hydro-mechanical...

Thermo-hydro-mechanical effects of hydraulic fracturing on depressurization-induced gas production from natural gas hydrate reservoirs: a numerical study

A MATLAB-based thermo-hydro-mechanical (THM) simulator incorporating the Snow equivalent-permeability tensor was developed for hydraulic-fracturing-assisted depressurization of natural gas hydrate reservoirs in a two-dimensional axisymmetric domain. Validation against Shenhu field-production data, TOUGH+Hydrate benchma...
