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...

Artificial ground freezing (AGF) is widely used for temporary ground improvement in underground construction. However, predicting freeze–thaw (FT) deformation remains challenging due to strongly coupled thermo-hydro-mechanical processes. Although applied vertical stress is generally expected to suppress frost heave, fi...

This research analyzed the impact of fine-grained content on the mechanical characteristics of coarse-grained soil in the river valley region of southeastern Xizang under freeze-thaw cycle circumstances via indoor tests, and modified the Duncan-Zhang model based on the test results. A total of six different coarse-grai...

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...
High embankments constructed from coarse-grained soils play an important role in transportation and infrastructure development, particularly in projects requiring substantial elevation changes. The deformation behavior of such embankments is governed by the combined effects of particle gradation, moisture condition, co...

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...
