A 10 m wide road is to be constructed across a site where the soil profile consists of 3 m of sand, overlying 1 m of peat, over a deep sand deposit. The water table is 1 m below the soil surface. The road pavement applies a uniform stress of 20 kPa to the underlying soil. The peat is lightly over-consolidated with an over-consolidation ratio of 1.25, has a uniform void ratio, e = 2.0, a re-compression index, Cr = 0.2, a compression index, Cc =1, and a specific gravity, Gs = 2.5. The sand can be assumed to be incompressible, with d = 17 kN/m3 and sat = 20 kN/m3 . Calculate the settlement beneath the centre and beneath an edge of the road.
The answer is 28.8mm beneath the centre and 6.4mm under the edge but I can't understand why.

The soil profile at a site consists of a clay layer 10 m thick,
sandwich between two sand layers. The top sand layer has a density
of 1.9 Mg/m3 and is 5 m thick. Below this layer is a 10 m thick
clay layer with a saturated density of 1.8 Mg/m3 and a saturated
water content 42%. The deeper sand layer has a saturated density of
1.9 Mg/m3 and extend to the depth investigated at the site. The

Problem No. 1 The soil profile at a site consists of a
top 4 m layer of dense sand followed by 2 m of clay, which is
underlain by a stiff stratum. The water table is at 2 m below the
ground level. The follow- ing data was obtained from a
consolidation test on an undisturbed sample obtained from the
middle of the clay layer: water content 36%, specific gravity of
the clay grains = 2.72, compression index = 0.72,...

A 3 m tall, 30 m wide, road embankment made of rockfill with a
unit weight of 20 kN/m3 is to be constructed over a 30 m thick
normally consolidated clay layer resting on a very permeable
fracture rock bed. The clay layer has a coefficient of
consolidation cv=7 m^2/month, and a unit weight of γsat=18.5 kN/m3.
The compression characteristics of the clay are mr=120, and
m=12.
a) Determine the time required for the remaining consolidation
to be 25 mm...

Q2) A trapezoidal wadi 3 m wide and 2:1 side slope is to cross a
road at station 1+120. The drainage area is 50-hectare consisting
of bare earth with steep slopes. A concrete box culvert is
considered to drain the wadi assuming 15 minutes concentration-time
and a 20-years return period.
Determine the minimum width of the culvert to the nearest 10 cm
assuming one meter maximum culvert depth, two meter allowable
headwater depth, 1% culvert slope (same as the Wadi...
