Test results demonstrate that the S-PVD method not only significantly enhances the ground reinforcement effect, effectively increasing surface settlement and vane shear strength of the soil, but also improves the uniformity of the reinforced soil, with only a 4.6 % difference in the vane shear strength between the top and bottom of the drainage board. In addition, the S-PVD method can meet the unloading criteria in less than 30 days, reducing the consolidation period by 34.1 %. The optimized S-PVD system demonstrates notable cost-effectiveness through energy-efficient operation and accelerated consolidation, achieving 26.5 % reduction in unit area cost of materials and electricity compared to conventional vacuum preloading.

The results show that the risk of particle erosion under cyclic flow is greater than the risk of system clogging, and the magnitude of hydraulic gradient and normal stress have an important influence on the filtration behavior. The boundary scour effect caused by the cyclic flow is proportional to the hydraulic gradient, while the normal stress enhances the retention of the soil through the benign geotextile blockage effect. The corresponding visual inspection analyses reveal that stable arching structures can be formed near the filter interface under cyclic flow, thus mechanically enhancing the stability of the system.

Furthermore, based on the full-scale experiment, a validated numerical model was developed, enabling a parametric analysis of the effects of reinforcement cross-sectional configurations, rock shapes, impact energy and impact points on embankment performance. The findings indicate that reinforced embankments exhibit excellent impact resistance, exhibiting two distinct deformation patterns upon impact that are primarily influenced by impact point, impact energy and reinforcement cross-sectional configuration.

When maintaining equivalent aspect ratios, flatter rock geometries generate stronger impact forces and cause more significant damage to the embankment structure.

The model is then implemented in ABAQUS, and validated against a realistic problem where the geogrid is embedded in soil. The influence of the orthotropy (against isotropy) on both the reinforcement and the overall soil–geogrid structure is evaluated. The results show that the orthotropic model can accurately predict the tensile response of the geogrid in different directions, with the orthotropy having a significant influence on the reinforcement and the overall structural response, especially in highly orthotropic materials. The study further examined stress redistribution capabilities in geogrids with notches, revealing enhanced stabilization performance using the orthotropic model. Parametric tests indicated that traditional isotropic assumptions might underpredict or overpredict reinforcement performance, emphasizing the advantages for accurate orthotropic characterization.
