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.

An oil tank is to be sited on a soft alluvial deposit of clay. Below the soft clay is athick layer of stiff clay. It was decided that a circular embankment, 10 m diameter,with wick drains inserted into the soft clay would be constructed to preconsolidateit. The height of the embankment is 6 m and the unit weight of the soil comprisingthe embankment is 18 kN/m3. The following data are available: thickness of softclay = 7 m, ks = 1 × 10−10 m/s and Ch = 0.6 m2/yr. The desired degree ofconsolidation is 90% in 12 months. Determine the spacing of a square grid of thewick drains. Assume wick drain of size 100 mm × 3 mm and qw = 0.1 × 10−6 m3/s.The flow point distance is 4 m. Assume a half-closed system.
