Question
write all step is clearly pls you give me different solution why
Transcribed Image Text:2. Bascd on the following figure, all layers shown in the figure are fully saturated.
The pressure applying from a building to the ground surface is about 900 kPa.
Assume Gs = 2.7 for each layer.
(a) Determine the cffective stress for a soil element at the middle of each layer.
(b) Determine the vertical stress increase at the middle of the clay layer under the
center of the foundation (10 mx20 m).
(c) Determine the primary consolidation settlement of the clay layer at the center
of the foundation if the clay is overconsolidated with an OCR=1.5.
(d) How long will consolidation settlement take for 50% consolidation to occur
in the field if the value of C, = 10 m2/year.
