Question

A specimen of a CL soil with a friction angle phi=28 and a preconsolidation stress sigma’p = 210 kPa is loaded one dimensionally to sigma’vc = 300 kPa. Estimate the value of sigma’hc at this load. If the specimen is unloaded one dimensionally by reducing the vertical stress, what is the theoretical limit to which sigma’vc can be reduced for at rest conditions to still apply? Estimate the value of sigma’hc at this limiting value of sigma’vc.
