Question:
Two samples of a slightly over-consolidated clay were tested in triaxial compression, and the following data at failure were obtained. The pre-consolidation stress for the clay was estimated from oedometer tests to be about 400 kPa.
(a) Determine the Skempton pore pressure parameter A at failure for both tests.
(b) Plot the Mohr circles at failure for both total and effective stresses.
(c) Estimate 2205' in the normally consolidated range, and c' and ∅' for the over-consolidated range of stresses.?
