DRAINED SAND BEHAVIOR IN AXISYMMETRIC TESTS AT HIGH PRESSURES

The authors present the results of an experimental investigation of granular materials at high pressures. Axisymmetric specimens of dense Cambria sand were tested in drained triaxial compression tests between confining pressures of 0.05 and 52 MPa. In addition, drained traixial extension tests between confining pressures of 0.25 and 52 MPa were conducted. The findings revealed that the stress-strain curve and volumetric and axial strains to failure rapidly increase at a certain stress magnitude when confining pressure is increased. The increase is directly related to a rapid increase in particle crushing. The stress-stain curves steepen and the volumetric and axial strains to failure decrease when stress magnitude goes beyond a certain higher value. This is attributed to the cessation of particle crushing and is typified by a zero rate of volume change at failure. The Mohr-Coulomb secant friction angle corresponds to the rate of volume change at failure, regardless of soil behavior and subject to large amounts of particle crushing.
