A 2m clay layer has values of e 0.92, Gs 2.72 and liquid limit of 40%. Above the clay is a 3m thick layer of sand with e = 0.50 and Gs 2.62. The water table is located 1.6m below the ground. If a 3m thick backfill is placed on the ground surface having a unit weight of 17.3 KN/cu.m. determine the following; 1. Compression index of clay 2. Effective pressure at the midpoint of clay 3. Primary settlement for normally consolidated 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.
