The medium gray silty clay of Fig. 8.23(b) at a depth of 20 m had an LL of 38 and a PL of 23. Estimate the following parameters for this soil:

(a) coefficient of earth pressure at rest;

(b) effective angle of internal friction;

(c) ratio of rfice.th,;

(d) activity;

(e) sensitivity; and

(f) the undrained Young's modulus. Are there any inconsistencies in the values you obtained? If so, discuss the possible reasons.
