摘要

This study investigates the deformation characteristics of the Xinyi highway slope under repeated freeze–thaw (F–T) cycles, with a particular focus on validating the effectiveness of joint reinforcement with anti-slip piles and frame anchors using three-dimensional finite element modeling. The numerical simulation results revealed that the initial leading-edge deformation of the slope was approximately 1.4 m, which was consistent with the field-measured values, thus validating the reliability of the numerical simulations. Localized displacements were primarily concentrated in the mid-slope and toe regions, indicating potential failure. Stabilization with joint reinforcement reduced the overall deformation, with the maximum horizontal displacement limited to 2.153 × 10⁻⁴ m, demonstrating effectiveness in enhancing slope stability. The axial stress distribution along the anti-slip piles showed significant variability, with compressive stresses reaching 143.97 MPa in the mid-depth sections, whereas tensile stresses as low as -135.18 MPa occurred near the shallow zones. The bending moment profiles varied across the slope, and the central and right-flank piles experienced higher bending demands. Pile head displacements showed a bell-shaped pattern, peaking at 9.3 mm for the central piles. These findings confirm the critical role of joint reinforcement in mitigating slope instability under F–T cycles, aiding in reinforcement optimization and long-term stability.
