A soil strata can be described as 6 meters of sand underlain by 4 meters of clay with the water table located 7 meters from the bottom of said strata. The sand has a dry and saturated unit weight of 14 kN/m3and 18 kN/m3 resp. On the other hand, pertinent clay properties are saturated unit weight of 19 kN/m3 , void ratio of 0.8 and liquid limit of 40. Compute the primary consolidation settlement considering the following conditions if a uniform load of 100 kPa is acting on the soil. If necessary, assume a logical value of Cs. A. The clay is normally consolidated. B. The pre-consolidation pressure is 190 kN/m2 C. The pre-consolidation pressure is 170 kN/m2.
