A $4\mathrm{.}5m$ high gravity retaining wall has to be designed to

retain soil to increase the useable areas on a site.

Design a suitable cross$-$section and Calculate the Factors of

Safety for overturning, sliding and bearing capacity.

The soil with a unit weight of $18k\frac{N}{m^3}$ and angle of internal

friction $=30.$

The coefficient of friction between the soil and the base is

$0\mathrm{.}55$ and the ultimate bearing capacity of the soil is

$430k\frac{N}{m^2}.$

The unit weight of the wall is $24k\frac{N}{m_{?}^3}$

You will then:

Discuss the methods and approaches used in

determining the sectional size and details of a

structural elements

Evaluate alternative design methods in terms of their

application.

Is anyone able to help with this?
