1 In a triaxial test a soil specimen was consolidated under a cell pressure of 600 kPa and a back pressure of 250 kPa. Then, under undrained conditions, the cell pressure was raised to 850 kPa resulting in a pore water pressure reading of 495 kPa; then (with the cell pressure remaining at 850 kPa) axial load was applied to give a deviator stress of 480 kPa and a pore water pressure reading of 620 kPa. Calculate the values of the pore pressure coefficients B, A and B. (B=0.98, A=0.26 and B=0.51)
