A building is constructed on a site underlain by saturated clay, normally consolidated. The excess pore water pressures measured at the centre of the clay layer 6 months after construction are significantly lower than that anticipated by 1-D Terzaghi’s theory of consolidation. What could be the reasons for the observed underprediction in the excess pore water pressure dissipation? Select all options that applies. A.3-D flow of water within the soil B.The compression index assumed in design is incompatible with the soil conditions encountered in the field. C.The coefficient of consolidation assumed in design was over-estimated D.The coefficient of consolidation assumed in design was under-estimated

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.
