1- (50 points) Consider the following soil profile. If a fill with unit weight of 120 lbf/ft3 and height of 10 ft is planned to be placed on the field, estimate: a) The primary consolidation settlement if the preconsolidation stress is 1100 psf. b) The degree of consolidation and the corresponding settlement six months after loading. c) The time (in minutes) that it takes for a 1-in-thick lab specimen of this soil to get to the same degree of consolidation as the field. d) The secondary and total consolidation 6 years after placement of the fill if the time to complete primary consolidation is 1.6 years.
