Abstract
Stress-deformation behaviour of sand reinforced with discrete randomly distributed fibres depends on the properties of the fibres and sand-fibre surface friction. This paper presents the results of triaxial compression tests, performed to determine stress-strain behaviour of fine sand reinforced with discrete, randomly distributed plastic fibres, and to observe the influence of fibre properties (i.e. weight fraction and aspect ratio) and confining stress on shear strength of reinforced sand. The results indicate that the sand-fibre composites have a curved or a bilinear failure envelope, with the break occurring at a certain confining stress, called the ‘critical confining stress’. The magnitude of the critical confining stress decreases with increase in aspect ratio of the fibres. The shear strength of plastic-fibre-reinforced sand increases with increase in fibre content and aspect ratio.
