In a tri-axial test, a soil specimen is allowed to consolidate fully under an all-round pressure of 200 kPa. Under undrained
conditions, the all-round pressure is increased to 350 kPa, and the pore water pressure at the time is measured as 144
kPa. Axial load is then applied under undrained conditions until failure takes place, and the following results are
obtained:
Axial strain (%) 0 2 4 6 8 10
Principal stress difference (kPa) 0 201 252 275 282 283
Pore water pressure (kPa) 144 211 228 222 212 209
Answer the following:
(i). Determine the value of pore-pressure coefficient B; and comment whether the test can be considered as saturated.
(ii). Plot the stress-strain (q- εs) curve for the test.
(iii). Draw the total and effective stress paths for the test.
(iv). Estimate the critical state friction angle for the soil
