Abstract

An experimental study of the effect of strain rate on the stability of granular soils at high pressures has shown that there is no apparent effect on the location of the instability line. However, during undrained triaxial compression tests the deviator stress, effective stress path, effective stress friction angle, and pore pressures are significantly affected by changes in strain rate. Strain rate effects during drained triaxial compression tests are also presented, but do not appear to be as significant as in undrained tests.
