Soil Mechanics - Consolidation

A 10 m thick clay layer is resting over a 3 m thick sand layer and is submerged. A fill of 2 m thick sand with unit weight of 20 kN/m³ is placed above the clay layer to accelerate the rate of consolidation of the clay la...

A 3 m thick clay layer is subjected to an initial uniform pore pressure of 145 kPa as shown in the figure. For the given ground conditions, the time (in days, rounded to the nearest integer) required for 90% consolidatio...
