Notes:

initial (or residual) effective stress in specimens in triaxial cell;

^†

volume change required to re-consolidate to in situ stress;

^‡

change in void ratio to initial void ratio required to re-consolidate to in situ stress;

^§

Young's modulus at 0·01% axial strain; and

^††

pore pressure parameter [Δu = Δσ₁ − D(Δσ₁ − Δσ₃)] used by Lunneet et al. (1997) to assess sample disturbance effects. Value at stress of 2/3 peak stress should be close to 0·0 for a perfect sample.
