For the soil profile shown below, calculate the final settlement due to the placement of the sand fill. Estimate the excess pore pressure at a depth of 1.5 m into the third clay layer 1.5 years after the fill is placed. Assume the coefficient of consolidation is Cv = 1.8 m2/yr. Fill y = 16.0 kN/m² (3m thick) Clay 1 (3m thick) Sand (0.5m thick) Clay 2 (2m thick) Sand (0.5m thick) Clay 3 (4m thick) Sand (0.5m thick) eo...

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...

A 5m wide and 10m long rectangular foundation is built on a site where the soil profile consists of 3m of gravel and 4m of clay overlying rigid impermeable rock as shown in Fiqure 8. The foundation carries a surcharge loading of q-65 kN/m2 Initially the water table is 1 m below the surface of the gravel. The water table rises to the surface of the gravel slowly over a period of time and the surface loading induces an increase...
