The water content of a sample of saturated soil at a mean effective stress of 10 kPa is 85%. The sample was isotropically consolidated with a mean effective stress of 150 kPa. At the end of the consolidation, the water content was 50%. The sample was then isotropically unloaded to a mean effective stress of 100 kPa, and the water content increased by 1%. Given: G, = 2.7.6' = 25ยบ. a) Calculate i and X. b) Determine the failure stresses (p'rand ) under CU test and CD test for the conditions
