Question

Please answer the following question with a step by step solution so I can follow and understand, explain theory 

1. ) For the square foundation below determine: a) ultimate settlement and b) settlement after 140
days due to consolidation of the clay layer. Base your calculations on the values at the midpoint of
the layer.
8 ft
12 ft
8 ft
16 ft
SAND (COARSE)
Y 110 pcf w=0.08
G₁= 2.65
q=2200 psf
ROCK
e=0.6
CLAY (NORM.CONSOL.)
c, = 0.15 ft/day
C₂ = 0.42
e₂ = 1.2
G₂ =2.57
a) Sult = D.126 ft
5140 = 0,087 ft
