A stratum of sand and a stratum of clay have the same thickness of 3 m. The coefficient of compressibility of sand is one fifth of coefficient of compressibility of clay and the permeability of sand is 10,000 times that of the clay. Assuming the same initial void ratio the ratio of the consolidation time for the clay to that of the sand for same degree of consolidation is

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.
