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.

During the construction of a housing project, it is estimated that the average permanent load on a clay layer located at 6 m below ground surface will increase by about 200 kPa. The average effective overburden pressure at the middle of the 4.5 m thick clay is 100 kPa. The result from soil sample testing givens the consolidation parameters eo = 0.96, Cc = 0.45, Cv = 2.5 m2/year, and the clay is in www normally consolidated condition. Estimate the total consolidation settlement that will happen and the time taken to achieve 90% consolidation stage.
