Abstract:
This article presents the results of innovative laboratory tests conducted on different types of cubic gabion boxes, each with approximate edge length of 1 m. The tests evaluated both confined and unconfined boxes subjected to compression stresses. In addition to the confinement factor, the experimental variables included the type of mesh, the presence of tie rods, and the apparent density. The primary goal was to conduct a comparative analysis of the deformability of the boxes by measuring their horizontal and vertical displacements under controlled conditions of uniformly distributed vertical loading. The results indicate that double-twist hexagonal mesh gabions, which are traditionally used in geotechnical applications in Brazil, can support less load. However, due to their woven mesh configuration and geometric characteristics, they exhibit greater flexibility, allowing for more significant deformations. In contrast, welded mesh gabions, which are square or rectangular and constructed with higher-strength, larger-gauge carbon steel wires, are capable of supporting higher loads. Comparative analyses of tests conducted with and without confinement revealed that, when the boxes are filled carefully, the tests without confinement can yield very satisfactory results in a simpler way.
