uhAssignment$-2/$Project $(10\%)$

Consider the cantilever retaining wall with the cross$-$

section shown in the adjacent Figure, which retains a

$2$ m depth of soil having the groundwater table at

$-1\mathrm{.}0$ m level.

Design Data and Parameters:

Soil Bearing Capacity, $q_{\text{a}\text{l}\text{l}}$ : $105$ kPa

Coefficient of Soil Friction, p: $30$

Unit Weight of Soil, ${}_s$:$17\mathrm{.}5k\frac{N}{m^3}$

$-$Unit Weight of Water, ${}_w$:$9\mathrm{.}81k\frac{N}{m^3}$

$-$Unit Weight of Concrete, ${}_c$:$2\mathrm{.}65k\frac{N}{m^3}$

Surcharge, $$:$11\mathrm{.}5k\frac{N}{m^2}$

$-$Ground Water Level: $-1$m from $0\mathrm{.}00$ level

Height of Surcharge, h: $0\mathrm{.}8$ m

Height of Wall: $2\mathrm{.}0$m

$-$f$\text{'}$c: $32$ Mpa

$-$fy: $460$ Mpa

concrete cover: $75$ mm

a$)$ Design the retaining wall with respect to stability in terms

of overturning moment, sliding, and slipping. Also check

the wall thickness against shear, bearing pressure under

the footing, and check the required length of the retaining

wall base. provide the reinforcement design.
