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: Gs = 2.7, ϕ′cs = 25°. a)
Calculate λ and κ. 10 b) Determine the failure stresses (p′f and
qf) under CU test and CD test for the conditions

Q4 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: Gs = 2.7, 6'cs = 25º. a) Calculate 1 and K. b) Determine the failure stresses (p'rand q) under CU test and CD test for the conditions.
