2.13 A normally consolidated clay layer

2.6m

thick has a void ratio of 1.3. Let LL

=41

and the average effective stress on the clay layer

=82k(N)/(m^(2))

. How much consolidation settlement would the clay layer undergo if the average effective stress on it increased to

120k(N)/(m^(2))

as the result of the construction of a foundation?
