Concept explainers

Calculation of Settlement

The vertical displacement of the structural foundation due to the loading from the superstructure is known as settlement. It is due to the reduction of air voids present in the soil. The amount of vertical displacement depends on the bearing capacity of the soil on which the foundation is laid. The effect of the settlement depends on the magnitude of settlement, uniformity, and the structural design of the structure. The maximum allowable settlement for residential and office buildings should be less than 18 mm, for industrial buildings, it is 38 mm and for commercial buildings, it is 25 mm.

Question

Identical surcharges are placed at ground
surface at sites X and Y, with soil conditions
shown alongside and water table at ground
surface. The silty clay layers at X and Y are
identical. The thin sand layer at Y is continuous
and free-draining with a very large discharge
capacity. If primary consolidation at X is
estimated to complete in 36 months, what
would be the corresponding time for
completion of primary consolidation at Y?
