A large embankment is to be built on the surface of a 18-ft clay layer. Before the embankment is built, the initial σ′v at the middle of the clay layer is 500 psf. The results from a 1-D consolidation test on the clay from the middle of the layer provide σ′p=1600 psf, Crε=0.0352, and Ccε=0.180. If the final σ′v at the middle of the layer after the embankment loading is 2000 psf, what is the settlement, in inches, of the clay layer resulting from this loading?

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.
