1.1 The average effective overburden pressure on a 10mts – thick layer in the field is 136 kN/m2 and the average voidratio is 0.98. If a uniform surcharge of 200 kN/m2 is applied onthe ground surface, determine the consolidation settlement for thefollowing cases, Cc = 0.35, Cs = 0.08.
a)Preconsolidation pressure, ?'p = 350 kN / m2 b)b)Preconsolidation pressure, ?'p = 150 kN / m2

1.2 For case b) of the previous exercise determine, a)What is the void ratio at the end of 100% of consolidation. b) IfCv = 1.5 mm2 / min, how long will it take to settle the first 100mm? Take the two-way drain for the clay layer.
