摘要: ABSTRACT The results of laboratory experiments performed to investigate the effects that factors such as fabric, anisotropic consolidation and stress-strain history have on shear modulus at very small strains (G0), drained degradation curve, cyclic undrained strength sands are summarized. presented show G0 is relatively insensitive sand initial stress ratio, monotonic prestressing, strain history. Thus, specimens with same can exhibit different behaviors in shear, depending upon their or To a lesser degree, this also true for (G) larger strains, interpreted conventional manner from tests (unload/reload modulus). Based these findings, limitations involved use G interpret behavior discussed.
