Triaxial Behavior of Sand Reinforced with 3D Reinforcements
In conventional reinforced soil, the reinforcements are put horizontally in the soil. In this paper, a novel concept of soil reinforced with three-dimensional (3D) reinforcements is proposed. In 3D reinforced soil, besides conventional horizontal reinforcements, some vertical and 3D reinforcements can also be laid in the soil. A series of triaxial tests on sand reinforced with one-layer 3D reinforcement (galvanized iron sheet and hard plastic sheet used) were carried out. The behavior of sand reinforced with different 3D reinforcing configurations on stress-strain relationship and shear strength is studied. From the experimental results, the comparison of stress-strain relationship and shear strength between horizontal reinforced sand and 3D reinforced one is analyzed. The influences of the height of vertical reinforcements, the kinds of reinforcement materials and confining pressure on strength of reinforced sand are discussed. The experimental results show that 3D reinforcement increases not only its cohesion but also the angle of internal friction significantly, especially with double-sided reinforcement.
