During the first stage of triaxial test when the cell pressure is increased from 0.10 N/mm2 to 0.26 N/mm2, the pore water pressure increases from 0.07 N/mm2 to 0.15 N/mm2. Skempton’s pore pressure parameter B is
A. 0.5
B. -0.5
C. 2.0
D. -2.0
Answer: Option A

B=Δu/Δσ' where, Δu=change in pore pressure and Δσ'= change in effective stress
Δu= 0.15-0.07= 0.08
Δσ'= 0.26-0.10= 0.16
B= 0.5
