Transcribed Image Text:5. A 3-m-thick wide granular fill (y = 20 kN/m³) is to be
placed on a site with a soil profile consisting of a 5.5 m clayey
silt layer (y = 17.8 kN/m³, e, = 1.25, C, = 0.5, ơ,/ơ,, = 5.2
C,IC. = 0.15) over 11.5 m of silty clay (y = 17.1 kN/m³, e,
= 1.48, C. = 1.66, ơ,lo = 1.4, C,IC. = 0.10, and
Ca/C. = 0.037) over granular till. The water table is at the
ground surface. Compute the settlement resulting from: (a)
primary consolidation of the clayey silt and (b) compression
of the silty clay after 100 years assuming that primary consolida-
tion is completed in 30 years.
