Through extensive on-site research of the plain concrete composite foundation for Jiuma Expressway, we conducted proportional scaling tests. Our study focused on temperature, moisture, pile-soil stress, and deformation this under freeze-thaw conditions. The findings indicate that temperature pile fluctuates sinusoidally with atmospheric changes. Vertically, as one moves deeper, average rises, amplitude variation reduces, delay in change increases. Horizontally, has a more pronounced effect side ditch slope toe than inner road, leading to variations Regarding volume moisture content, both content within embankment pore pressure experience cyclical changes during process. Specifically, they decrease freezing increase thawing. Moisture tends move towards front located at slope's base embankment's summit. In terms actual stress ratio exhibit line soil's cycles, prominent alterations shoulder position. Lastly, concerning deformation, road section displays deformations toe. Foundations inclined shallower frost depths will display differential settlements same tilt. If depth impacts body, tensile compressive strains throughout cycles.
