A normally consolidated clay layer 4.91 m. thick has a void ratio of 1.12. Liquid limit is equal to 35 and the average effective stress on the clay layer was 81 kPa. The average stress on it is increased to 125 kPa. as result of the construction of a foundation. If the clay layer is preconsolidated, compute the consolidation settlement in millimeters if the preconsolidation pressure is 93 KPa. Use Cs = 1/7Cc.

Question
A normally consolidated clay layer 4.91 m.
thick has a void ratio of 1.12. Liquid limit
is equal to 35 and the average effective
stress on the clay layer was 81 kPa. The
average stress on it is increased to 125
kPa. as result of the construction of a
foundation. If the clay layer is
preconsolidated, compute the
consolidation settlement in millimeters if
the preconsolidation pressure is 93 KPa.
Use Cs = 1/7Cc.
