In a triaxial test, a soil sample was consolidated under a cell pressure of 700 kN/m² and a back pressure of 350 kN/m². Thereafter, with drainage not allowed, the cell pressure was raised to 800 kN/m² resulting in the increased pore water pressure reading of 440 kN/m². The axial load was then increased to give a deviator stress of 570 kN/m2 (while the cell pressure is 800 kN/m²) and a pore pressure reading of 650 kN/m².

Transcribed Image Text:In a triaxial test, a soil sample was consolidated under a cell pressure of 700 kN/m² and a
back pressure of 350 kN/m². Thereafter, with drainage not allowed, the cell pressure was
raised to 800 kN/m² resulting in the increased pore water pressure reading of 440 kN/m².
The axial load was then increased to give a deviator stress of 570 kN/m2 (while the cell
pressure is 800 kN/m²) and a pore pressure reading of 650 kN/m².
