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.

A dilatometer test (DMT) was conducted in a clay deposit. The water table was located at a depth of 3 mbelow theground surface. At 8 m depth the contact pressure (p1) was 280 kPa and the expansion stress (p2) was 350 kPa.Assume σo = 95 kPa at the 8 m depth and μ = 0.35.

A 3 meter thick fill was placed over a 9 meter thick compressible clay. Underlying the clay layer is a very hard impermeable clay. The groundwater table is located on top of the compressible clay. A circular tank 9 meters in diameter transfers a surface contact stress of 45 kPa. Assume for this problem that the settlement of the fill and the very hard clay is small compared to the settlement of the compressible clay. a) Calculate the initial void ratio and saturated density of the compressible clay. b) Divide the compressible layer into two sublayers of equal thickness. The preconsolidation pressure is 100 kPa for the upper sublayer and 160 kPa for the lower sublayer. Calculate the following at the center of each sublayer: the increase in vertical stress caused by the tank underneath its center, and the consolidation setttlement due to the combined effect of the tank and weight of fill. c) How long will it take for 0.18 meters of settlement to occur? d) After 3.6 years, what…
