4. A normally consolidated clay layer is 3 m thick (one way drainage). From the application of a given pressure, the total anticipated primary consolidation settlement will be 80 mm. a. What is the average degree of consolidation for the clay layer when the settlement is 25 mm? b. If the average value of Cv for the pressure range is 0.002 cm²/sec, how long in days will it take for 50% settlement to occur? Tso= 0.197. How long in days will it take for 50% consolidation to occur if the clay layer is drained at top and bottom? C.

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.
