Question

office building. It is expected that the vertical stress at

the top of the clay will increase by 150 kPa and at the

bottom by 90 kPa. Assuming a linear stress distribution

within the clay, calculate the consolidation settlement.

(Hint: You should divide the clay into five equal layers,

compute the settlement for each layer, and then find the

total settlement.) Groundwater level is at the top of the

clay layer. An oedometer test on a sample of the clay

revealed that 90% consolidation on a 20-mm-thick sample

occurred in 40 minutes. The sample was drained on

the upper and lower boundaries. How long will it take

for 50% consolidation to occur in the field?

Not able to see the picture. Kindly post the link to the picture in comments so that i can help.
thank you.
