| 英文摘要 | This study examines the adfreeze behavior between the soil and sand-coated geotextile (SCGT) interface using a temperature-controlled direct shear apparatus under constant normal stiffness (CNS) conditions. The experimental program systematically investigated the effects of surface roughness, initial normal stress, freezing temperature, moisture content, and normal stiffness, while digital image correlation (DIC) was employed to quantify local deformation mechanisms. Results show that increasing surface roughness markedly enhances interface shear strength at low temperatures, primarily through an increase in apparent cohesion associated with stronger particle interlocking and migration of the shear plane into the soil. Specifically, the apparent cohesion increased from 6.9 to 25.9 kPa at 20 degrees C and from 22.9 to 59.9 kPa at -8 degrees C as the surface roughness increased from smooth to very rough. Under subzero temperatures, this roughness-induced reinforcement is further amplified by cementation ice, producing strain-softening behavior compared with the shear-hardening response observed at ambient temperature. Mesoscale analyses indicate that higher roughness intensifies strain localization and increases shear band thickness, underscoring the critical role of roughness in controlling interface deformation and strength. These findings provide mechanistic insight and design-relevant parameters for reinforced geotextile applications in cold-region geotechnical engineering. |
