Constitutive Behavior of Fabric Vs. Fiber Reinforced Sand.

Laboratory triaxial compression tests were performed to determine the stress-strain response of sand reinforced with continuous, oriented fabric vs. discrete, randomly oriented fiber, and to observe the influence of various inclusion properties, soil properties, and test variables on the constitutive behavior of fabric or fiber reinforced s and . Uniaxial compression tests were also run on encapsulated s and specimens to examine the effect of external fabric encapsulation on the constitutive behavior of internally reinforced granular materials. Fabric inclusions markedly increased the ultimate strength, increased the axial strain at failure; and in some cases, limited reductions, in post peak shearing resistance. At very low strain (
