Stress-Dilatancy Relationship for Fiber-Reinforced Soil
Abstract Polypropylene fiber inclusion clearly increases soil shear strength and reduces the loss in strength post-peak. Stress-dilatancy relationship plays an essential role in constitutive modeling for soils. The increase in the effective confining stress provided by the fibers can be deduced from comparing the stress-strain and strength behavior of reinforced soil and pure soil. When a polypropylene fiber-soil assembly dilates in response to applied shear deformations, the work done by the driving stress will be dissipated by not only particle sliding but also the fiber deformation. The stress-dilatancy relationships in conventional triaxial compression, extension conditions were discussed in this study. The stress-dilatancy relationship is validated against a series of triaxial tests on Nanjing sand mixed with discrete polypropylene fibers.
