摘要

Welded wire mesh gabions provide a rigid alternative to traditional woven systems, allowing the use of alternative fills such as sand, gravel, and compacted soil in addition to rock. This flexibility facilitates the use of local materials, which is particularly valuable in emergency situations where conventional rockfill may be unavailable. This study evaluated the performance of welded gabions under compression using 0.4 × 0.4 × 0.4 m boxes filled with loose sand, compacted sand, crushed stone, and gabion rock. Parameters analyzed included compressive strength, displacements, and stiffness moduli. Gabion rock and crushed stone exhibited the highest strengths (470 and 400 kPa, respectively) but also showed greater deformations. Compacted sand performed moderately well, combining reasonable stiffness with low displacement. Loose sand had the lowest strength but demonstrated higher initial stiffness. Overall, coarse materials in welded mesh gabions displayed superior structural performance compared to woven mesh systems, supporting their use with alternative fills in slope stabilization, debris control, and temporary retaining structures.
