ABSTRACT

 

Soil reinforcement is an effective and reliable technique for improvement of strength and stability of soils. Traditional soil reinforcing techniques involve the use of continuous planar inclusions oriented in a preferred direction to enhance strength and stability. In the past few decades, randomly distributed fibre reinforced soil mechanisms have been studied extensively for geotechnical engineering applications.Unlike soil structures reinforced with planar inclusions, soil structures reinforced with randomly distributed fibres are still conventionally designed using composite approaches. A number of experimental studies have been reported on fibre-reinforced soil by several researchers. Several composite models have been proposed by them to explain the contribution to shear strength from randomly distributed fibres within a soil mass. This paper presents a review of the available literature explaining the mechanisms and predictive models for shear strength behaviour of fibre-reinforced soils.
