The results of unconfined compression tests on a sample of clay in both the undisturbed and remolded states are summarized below. Determine the compressive strength, the initial tangent modulus of deformation, and the secant modulus of deformation at 50% of the compressive strength fot both the undisturbed and remolded specimens. Determine the sensitivity ol the clay. For the solution of a practical stability problem involving this clay in the undisturbed state, what shear strength would you use if no change in water content occurs during construction? (Alter A.
