Question
Ex Two identical soil samples (A) and (B) of a fully saturated N.C.C.
were tested. Sample (A) was subjected to an unconfined compression
test and failed when the deviator stress (OT-13) was (200) kN /n².
Sample (B) was tested under UU conditions with a cell pressure
of (300) kN/m². The pore water pressure
at failure.
was (200) kN/m².
a) What was the pore water pressure at failure in sample (A).
b) If C=o, Find (2) for this clay.
(Itint. Start with soil B, and that (OJ) un= (FJ) afined).
