Freeze-thaw effects can significantly alter the volume of expansive soil due to water-phase change and expansion. The montmorillonite content was an important factor influencing expansibility soil. This paper investigated micropore structure characteristics under freeze-thaw cycles with various contents. In addition, evolution soils relationship between unfrozen water temperature were also examined via X-ray diffraction (XRD) nuclear magnetic resonance (NMR). results indicated that: (1) affected pore size distribution soil, increasing content, relaxation time (T2) curves changed from single-peak into double-peaks; (2) after multiple cycles, macropores in increased mesopore pores decreased; (3) considering freezing point capillary adsorption, characteristic curve (SFCC) could be divided four stages, namely, water, free freezing-capillary freezing-hydroscopic water; (4) only 0°C −5°C, while at temperatures lower than effect on negligible.

Frozen soil is a vital component of the cryosphere and sensitive to climate changes, accelerating thaw when anthropogenic warms. Identifying state freeze/thaw crucial for effective water resource management, cold region engineering construction, agriculture development, etc. In this study, we used Landsat remote sensing images data identify frozen soil, focusing on eastern Tibetan Plateau (ETP) as case study. We compared target detection models two architectures semantic segmentation model framework four with different encoders. Mean Pixel Accuracy (MAP), Intersection over Union (MIoU), Taylor diagrams, surface borehole metrics analyze model's accuracy. Our results showed that YOLOv8-Large performed better than other models, MAP50 0.53. The ResNet34 encoder in demonstrated highest accuracy 86.92%, effectively resisting interference, could freeze–thaw higher noisy images. study provides high-resolution pathway soils, which can benefit studies science, hydrology, ecology change.
