The soil profile at a site consists of 3 m of sand (ym = 17.5 kN/m³, ysat = 18.9 kN/m³) underlain by 6 m of clay (w = 27%, Gs = 2.70, mv = 0.32 MPa ¹, Cx=4.9 mm²/min), which is underlain by bedrock. The water table lies 1 m below the ground level. A 3 m-high compacted fill (ym = 20 kN/m³) is placed on the ground in an attempt to raise the ground level. a. What would be the final consolidation settlement of the clay layer? b. How long will it take for a 50 mm consolidation settlement to occur? c. What would be the consolidation settlement in one year?

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.
