In the figure below, the natural soil profile consists of sand
overlying clay overlying sand overlying bedrock. A
water table is present 1 m beneath the surface of the natural
ground. If 4 m of consistent fill material (γfill = 15
kN/m3) was placed on top of this soil profile that covered a
large area, determine:
(a) The consolidation settlement of the clay layer (using 4
equal layers in your calculation), and
(b) The time (in days) for this consolidation...

5, A soil element inside a 20° natural soil slope carries total vertical stress (%) of 140 kPa, total horizontal stress (on) of 80 kPa and shear stress (Tvh) of 15 kPa Canticlockwise shear stress on vertical plane). The pore-water pressure (u) inside the element is 30 kPa. The critical state angle of friction of the soil is 30o and its undrained shear strength is 40 kPa.

. A long natural slope in fissured overconsolidated clay is inclined to the horizontal with an angle =15 o . The saturated unit weight of clay is 18 kN/m3 . The water table is at the surface and the seepage is roughly parallel to the slope. A slip has developed on a plane parallel to the surface at the depth of 4.0 m. Find the factor of safety along the slip plane, for the following two cases: a. Peak shear...
