Question $2$

Part $($a$)$

You are working for an engineering consultancy and have been asked by your client to design a

retaining wall, as shown in Figure Q$3.$The unit weight of the soil is $19k\frac{N}{m^3}$and it has an

effective cohesion $c^{\text{'}}=0$and friction angle ${\phi }^{\text{'}}=35°.$Plot the distribution of active pressure on

the wall surface shown and then calculate the thrust on the wall and also determine the point

of application of each load $($distance above the base of the wall$).$Assume the water table is well

below the base of the wall.

Part $($b$)$

Check the stability of the wall against overturning, assuming the unit weight of concrete is $24$

$k\frac{N}{m^3}$and using a factor of safety of $1\mathrm{.}5$against overturning.
