Calculate how long it will take for consolidation to be almost completed (reach ca. 95% of ultimate consolidation) for layers of Bay mud with thickness of 1, 3, and 10m. Note that this happens when Terzaghi’s time factor reaches 1. Assume that the layers are drained both up and down during consolidation. The equation for the time factor is: inserted image Assumet hat the consolidation coefficient of the Bay mud is 10-8 m2/s.

Consolidation parameters

Consolidation is the process of expulsion of pore water present in the voids of soil solids under the pressure of the applied load. This is a quick process in the case of coarse-grained soils since the permeability is high due to the presence of more voids, while it is a slow and gradual process in the case of clayey soil as the permeability of clay is less. An example of consolidation is the settlement of soil under a building due to the load coming from the building.
