A building is to be constructed on a 6 m thick stratum of the clay for which consolidation data are given in Problem 1. a) The average in-situ void ratio of this clay stratum is 0.91 and initial effective vertical stress on this clay stratum is 200 kPa. Given that the average stress in the clay after construction of the building is 300 kPa, estimate the decrease in the thickness of the clay stratum caused by full consolidation under the building load; b) What would the decrease in the thickness of the clay stratum be if the initial effective stress on this clay stratum were 50 kPa? The initial void ratio is also assumed to be 0.91. c) Show on the e-logo' plot of Problem 1 the values of Ae used for making the estimates in (a) and (b).

Question
Transcribed Image Text:A building is to be constructed on a 6 m thick stratum of the clay for which consolidation
data are given in Problem 1.
(a) The average in-situ void ratio of this clay stratum is 0.91 and initial effective vertical
stress on this clay stratum is 200 kPa. Given that the average stress in the clay after
construction of the building is 300 kPa, estimate the decrease in the thickness of the clay
stratum caused by full consolidation under the building load;
(b) What would the decrease in the thickness of the clay stratum be if the initial effective
stress on this clay stratum were 50 kPa? The initial void ratio is also assumed to be 0.91.
(c) Show on the e-logo' plot of Problem 1 the values of Ae used for making the estimates in
(a) and (b).
