Abstract
To evaluate the stress-strain and strength anisotropy, CIUC, CIUE, CK0UC and CK0UE tests on recomposed soft clay were carried out under different consolidation pressures in normally consolidated stress state. Strength anisotropy due to change of consolidation methods has been observed mainly in total stress condition. Apparently, the non zero cohesion values have been observed in extension tests in both consolidation methods. The curves of undrained strength ratios between extension and compression tests in respect to consolidation pressures decrease under lower stresses and it may become constant under higher stresses.
