Abstract: To investigate the effects of the initial conditions and stress states on the intrinsic undrained strength behaviors of reconstituted clay, a series of consolidated undrained triaxial compression tests are performed on reconstituted Wenzhou clay under different consolidation conditions. The undrained shear stress-strain relationship and undrained strength are investigated. The void index I_v and the undrained strength ratios R^*_su=S_u/ p’ with different mean effective stresses p’ are used to compare the undrained strength S_u under different consolidation conditions with the Chandler intrinsic strength line IS_uL. The results indicate that the undrained shear stress-strain curves change with the consolidation stress paths under the same mean effective stresses p’. The undrained shear strengths and undrained strength ratios R^*_su=S_u/ p’ are also greatly affected by the consolidation stress paths. When S_u/ p’=0.33, the relationship between the void index I_v and the undrained strength S_u is identical to the Chandler intrinsic strength line IS_uL.
