Abstract: In view of the lack of research on the seismic influence degree of the back-wrapped panel type on the reinforced loess slope, three sets of shaking table model tests of the back-wrapped reinforced soil slope were carried out.The response differences of different backpacking processes (C-shaped wrap-around facing, Secondary reinforcement wrap-around facing and Self-wrap-facing) to reinforced loess slopes were explored.The experimental results demonstrate that the slope reinforced with C-shaped wrap-around facing exhibited the highest integral seismic resistance. The acceleration amplification factors along the slope height increased nonlinearly and peaked at the crest across all models.The C-shaped wrap-around facing provided the most effective mitigation of acceleration amplification, reducing the crest amplification factor by approximately 3–8% compared to the other two types. The failure patterns consistently combined outward deformation of the slope face and crest settlement. The C-shaped configuration displayed a notably smaller failure zone and superior overall seismic performance. Crest settlements followed a nonlinear distribution with greater values at both ends and minimal deformation in the central region. The self-wrap-facing system, due to relatively weak restraint in the top wrap-around section, showed a pronounced tendency for reinforcement pull-out under intense shaking, leading to the most severe damage. This model recorded the largest total permanent displacement (25.9 mm, representing 2.59% of the slope height H) and maximum cumulative settlement (39.9 mm, or 3.99%H) at the crest.Regarding reinforcement strain, peak tensile strain increased with rising PGA, with lower strains measured in the bottom geogrid layers. The C-shaped wrap-around facing registered the lowest overall strain levels, with a maximum peak strain of 0.10%, equivalent to 83.3% of those in the secondary reinforcement and self-wrap-facing models. The secondary reinforcement type performed most effectively in reducing internal backfill settlement, though stress relaxation was observed near the slope face. These findings offer valuable insights for the optimized design and typological selection of reinforced loess slopes in seismic regions.
