Transcribed Image Text:4. Calculate the total settlement of two clay
layers? The two clay samples at Location
A and Location B were collected and
analyzed. Use information at Location A
to estimate the settlement at the stiffy silty
clay. Use information at Location B to
estimate the settlement at the very stiff
clay. Compression index C, at point A is
0.25, C, at point B is 0.2. Swelling index
C, at point A is 0.08, C, at point B is 0.06.
Initial void ratio eo at point A is 0.66, eo at
point B is 0.45. Maximium vertical stress
cat point A is 101 kPa, at point B
is 510 kPa. The 8.5 m thick proposed fill
generated a increase of vertical stress
= 20.3x8.5 = 172.55 kPa.
