- Abstract:
- Traxial test were carried out to research the stress-strain relationship and strength property of flax fiber-reinforced sand. The variation of shear strength indexes of flax fiber-reinforced sand in different flax fiber content and different confining pressure was investigated. And the frictional mechanism between the flax fiber and sand in the shearing process was studied. The laboratory test results showed that, the strength and the capacity for resisting the deformation of flax fiber-reinforced sand were better than those of pure sand. Compared with the pure sand, the shear strength indexes of flax fiber-reinforced sand were changed, the cohesive and friction angle were increased, while the friction angle increased relatively less, the cohesive force increased greatly; in the certain number of rate of water and fiber length, the value of deviator stress, shear strength and cohesion firstly increased and then decreased with the increase of flax fiber content, and there existed an optimum fiber content.
