Abstract
Undrained monotonic compression and extension strain-controlled triaxial test are conducted on very loose Hostun RF sand specimens. The samples are subjected to initial isotropic or anisotropic consolidation. The instability lines of Lade are identified and it is shown that the peak strength envelopes depend on the consolidation history. Under conditions of compression and extension stress path, the steady state line, in (e-logp') plane, is not unique. Both for compression and extension tests, one can determine an upper limit line (UF) and a lower limit line (LF) with an identical slope. The minimum undrained shear strength is associated with the lower limit line LF. Finally, the necessary conditions for the soils to reach one of these lines are analyzed.
