ABSTRACT
A vertical line is drawn in Fig. 18.5 atpo = 0.8 ton/ft2• Point A is the intersection of the vertical line and the virgin curve giving the value of eo = 0.68. Po + lip = 0.8 + 2.2 = 3.0 t/ft2• At (Po + lip) =3 ton/ft2, we have (from Fig. 18.5)
lien = 0.68 - 0.62 = 0.06 liec = 0.62 - 0.48 = 0.14
From Eq. (18.3)
s\ = AenHe = 0.06 x 30 x 12 =12.86 in. l+eo 1+0.68
Total settlement Sc = 42.86 in. The total settlement would be reduced if the thickness of the collapsible layer is less or the
foundation pressure is less.
