An oedometer test is conducted for a soil sample. The sample is consolidated under vertical stress of 50 kPa. The oedometer test finished at 144 min and data are given in table I. The average thickness of the sample is 20 mm. Predict the coefficient of consolidation (cv, in mm^2/min) using Casagrande log t method and Taylor square root of t method. Please use the empty graphical papers.

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.
