A 10-ft-thick clay layer is drained at the top and bottom. Its characteristics are Cvr = Cv (for vertical drainage) = 0.042 ft2/day, rw = 8 in., and de = 6 ft. Estimate the degree of consolidation of the clay layer caused by the combination of vertical and radial drainage at t = 0.2, 0.4, 0.8, and 1 year. Assume that the surcharge is applied instantaneously, and there is no smear.

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.
