Figure $1$ shows a soil profile. The uniformly distributed load on the ground surface is

$p.$ Given: $p=1000l\frac{b}{f}{t}^2,H_1=8ft,H_2=15ft,$ and $H_3=17ft.$ Also,

Sand: ${}_{\text{d}\text{r}\text{y}}=110l\frac{b}{f}{t}^3,{}_{\text{s}\text{a}\text{t}}=115l\frac{b}{f}{t}^3$

Clay: ${}_{\text{s}\text{a}\text{t}}=120l\frac{b}{f}{t}^3,LL=50,e=0\mathrm{.}9$

Estimate the primary consolidation settlement if

a$.$ The clay is normally consolidated

b$.$ The preconsolidation pressure is
