Question B2a A clay experiences virgin loading from state 1 to state 2. At the initial state, state 1, the stress values are (p'=260 kPa, q=22 kPa), and the initial voids ratio e is 1.16. At state 2, the stress values are (p'=420 kPa, q=105 kPa). The values of compression indexes of the soil are lambda = 0.12 and kappa=0.03. Soil compression indexes lambda and kappa are determined from the Skempton compression model. The incremental shear stress for loading from state 1 to 2 is Answer:
