A retaining wall is to be constructed on a site shown in Figure. The concrete retaining wall's dimensions are designed as $B_1,B_2,B_3,H_1,H_2,$ and $H_3.$ The unit weight of the concrete to be used is $23\mathrm{.}5k\frac{N}{m^3}.$ Friction coefficient between the wall and the foundation soil is $0\mathrm{.}8.(Y===1\mathrm{.}8k\frac{N}{m^3})$

Hint: You may construct a table including pressures, forces, moment arms and moments.

Q$1)$ Determine all the forces acting on the wall $($by showing pressure distributions$).$

Q$2)$ Determine resulting moments.

Q$3)$ What is the factor of safety against both sliding and overturning?

Q$4)$ Write a conclusion about the design of your concrete retaining wall?
