What would be the settlement of the same structure in Problem 8-21 if the overconsolidation ratio of the clay were 1.0 and (4,„ + Dao= 270 kPa at the middepth of the clay layer? Show your work and assumptions on the e versus log a curve of Problem 8-20.

Problem 8-21

Use the consolidation data from Problem 8-20 to compute the settlement of a structure that adds 150 kPa to the already existing overhurden pressure of 120 kPa at the middle of a 6 m thick layer.

Problem 8-20

Plot the following void ratio versus pressure data, and evaluate the compression index and the recompression index. Determine the preconsolidation stress.
