The influence of effective consolidation stress on the normalized extension strength properties of resedimented Boston blue clay

[摘要] (cont.) The results also show that the maximum secant modulus (Emax) was found to decrease exponentially with the vertical consolidation effective stress ([sigma];;vc) according to the equation: Emax = 450 x [sigma];;vc 0.74 This relationship was proposed by Santagata (1999) and was presented as: Emax [alpha] [sigma];;vc 0.74. There is not any apparent relationship between the lateral stress ratio and the vertical consolidation stress. The trends observed during shear in extension are consistent with observations made during Ko consolidation compression testing.
