1. A wide fill will apply a uniform pressure of 100 kN/m2 to the surface of a soil profile consisting of 3 m of weathered clay (y = 17.6 kN/m³, e, = 1.2, C = 0.5, ơ, = 5, C,IC = 0.2) over 7 m of marine clay (y = 16.0 kN/m³, e, = 1.8, Ce = 1.5, o,lo, = 1.8, C,/C = 0.1) over 5 m of lacustrine clay (y = 16.3 kN/m³, e, = 1.7, C = 1.2, o,l CalC = 0.05) over granular till. The water table is 3 m below ground surface. Compute settlement resulting from primary consolidation of: (a) weathered clay and (b) marine clay.

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.
