Question
Transcribed Image Text:The soil profile at a site up to a depth of
10 m 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
instantaneously.
