Abstract
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 loess during F-T cycles at different initial moisture levels (13%, 16%, 19%). Results show that geogrids disrupt heat flow, creating a temperature buffer, while high moisture slows cooling. The geogrid cut maximum frost heave by 33.6% at 16% moisture but did not change its depth. Thaw settlement changed from a single peak to two peaks, showing the geogrid splits the soil into separate zones. Major water movement to deep soil only happened with high initial moisture. These results explain how geogrids reduce frost heave, aiding better design for cold-region construction.
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...

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...
Excess soil water in seasonal frost regions drives pavement deterioration through frost heave and thaw weakening. Thus, fast and effective drainage is crucial for preventing freeze-thaw induced damage. This extended abstract presents a preliminary element-scale laboratory comparison of a Wicking Nonwoven Geotextile (WN...

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...
