Question
Transcribed Image Text:The soil profile at a site up to a depth of 10m is
shown in the figure (not drawn to the scale). The
soil is preloaded with a uniform surcharge (q) of
70 kN/m2 at the ground level. The water table is
at a depth of 3 m below ground level. The soil unit
weight of the respective layers is shown in the
figure. Consider unit weight of water as 9.81 kN/
m3 and assume that the surcharge (q) is applied
instaneously.
q = 70 kN/m?
