Question
Below Figure represents the average soil profile obtained from boreholes, at
the site of a proposed building whose foundation is to be placed at a depth of 2.5m. The
ground water table is at a depth of 3.5m. It is estimated that the additional stress on the
N
clay layer due to the weight of the building will be 150k at the top of the clay and
m
N
70k at the bottom of the clay. Following results were obtained from consolidation
m
tests:
N
Unit weights: sand above water table -19.0k- 3i saturated sand -21.0k-
m
N
lay - 19.5k-
