A retaining woll is to be constructed on a site shown in Figure. The conctete retaining woll's dimansions are dasigned as $B_1,B_2,B_3,H_1,H_2$ ond $H_3.$ The unit weight of the cancrete to be used is $23\mathrm{.}5k\frac{N}{m^3}.$ Friction coefticient between the woll and the foundation snil is $0\mathrm{.}8.$ Ywoter $=9\mathrm{.}8k\frac{N}{m^3}.$

Hint $=4$o$,$ mey construct a tab$6$ incluiding pressures, forcos imoent orms and moments.

$Q_1-$ Determine all the forces actiong on the woll $($by showing pressune distributions$)$

$Q_2=$ Determine resulting morents

$Q_3=$ What is the factor of sofety agoinst both sliding and overturning?

Q $4=$ Write a conclusion cbout the design of your concrete retaining wall?
